[[folder:Characters Introduced in Season 1]]
!Julia Houston (Creator/DebraMessing)
Book writer and lyricist of the creative team, Julia is a talented and successful writer whose personal and professional lives often clash, sometimes with disastrous results.

* TenMinuteRetirement: Starts out the series this way, having promised her family to take time off but almost immediately getting drawn back in by the idea of a Marilyn Monroe musical.
* AuthorAvatar: Rumored to be an avatar of sorts for series creator Theresa Rebeck (leading to some controversy surrounding her character after Rebeck's departure).
* BettyAndVeronica: The Archie to Frank's Betty and Michael's Veronica, and vacillates between her conflicting attraction to them both for most of Season 1.
* BigSisterInstinct: In the surrogate family that is the ''Bombshell'' team, Julia tends to act as the protective big sister. She and Tom, in particular, tend to toggle back and forth over who is the reassuring older sibling and who is the mess of a younger sibling at the moment. She also develops a motherly or sisterly fondness and protectiveness for Kyle in Season 2.
* BrokenPedestal: From her son Leo, following his discovery of her affair with Michael.
* ComfortFood: Her go-to foods include marshmallow fluff (straight from the jar, natch) and dim sum.
* DeadpanSnarker: Julia, following [[spoiler: the rehearsal in which everyone finds out that Rebecca Duvall can't sing.]]
--> '''Eileen:''' What we need is a constructive solution!
--> ''beat''
--> '''Julia:''' Group suicide?
* DysfunctionalFamily: Between their adoption struggles, the strain Julia's career is causing, Leo's rebellious stoner tendencies, and Julia's affair, the Houston household is anything but smooth sailing.
* EasilyForgiven: Averted. The fallout from her affair hurts her family, her work family, and the production as a whole, and no one pulls any punches about reminding her of that.
* FieryRedhead
* HappilyMarried: To Frank, at the beginning of the series. [[spoiler: It doesn't last.]]
* LoveHurts: Falling for Michael leads to nothing but trouble for her family life and even bleeds into her professional life, due to their working relationship.
* LoveTriangle: With Frank and Michael Swift. [[spoiler: The finale implies she and Michael get back together]].
* MamaBear: Drops everything if Leo is in trouble, and goes to over-the-top lengths to find out where he is [[spoiler: when he runs away.]]
* MostWritersAreWriters: Julia (like series creater Theresa Rebeck) is a playwright.
* OneHourWorkWeek: Averted; Julia and the rest of the team spend a realistically large proportion of time either at rehearsals or working on the musical.
* PlatonicLifePartners: With Tom.
* ScarfOfAsskicking: Not so much. Julia's perpetual choice of unflattering scarves is even lampshaded during Season 2.
* StarvingArtist: Averted; we meet Julia at the point in her career where she is already a successful writer.
* ShipperOnDeck: Goes so far as to actually make reservations to force Tom and Sam to go on an actual date instead of just flirting in the rehearsal space.
* TearsOfFear: When her son, Leo, runs away from home.
* YourCheatingHeart: Twice, with actor Michael Swift.

!Derek Wills (Creator/JackDavenport)
[[caption-width-right:300:"No matter what happens next don't ever doubt you are a star."]]
The no-holds-barred director and choreographer with brilliant visions but a serious disregard for others. Has a nasty past with Tom and puts his work above all else.

* TheAlcoholic: Often turns to drinking when having problems. All he does for several days just before the Tony awards is sleep and drink.
* AmicableExes: Settles into this with Ivy for parts of Season 2.
* TheAtoner: After his mistakes catch up with him, he spends the last few episodes of the series trying to do everything in his power to make up for it.
* BadassLongcoat: Derek has quite a few. They resemble like those of another [[Series/DoctorWho famous Brit.]]
* BroodingBoyGentleGirl: A moody workaholic who finds himself attracted to both the naive Karen and the placating Ivy.
* TheCasanova: Has a reputation as quite a playboy, particularly when young and pretty performers are concerned. Hooks up with multiple characters on the show, and is stated to have had ''many'' other affairs off-screen.
* CastingCouch: Sleeps with two of his three Marilyns, and comes ''thisclose'' to the third, as well as several others (which eventually comes back to bite him in a ''big'' way). He genuinely does fall in love with Ivy, though.
* DeadpanSnarker: Has a dry comeback for every occasion, particularly directed at Tom and/or Jimmy:
-->'''Jimmy''': Lea Michele? ''Lea Michele?''
-->'''Derek''': If you say it one more time, she magically appears!
* HandsomeLech: More than happy to use his rakish good looks to bed a pretty chorus girl or leading lady.
* HeterosexualLifePartners: Used to be this with Tom, apparently.
* InsufferableGenius: Derek is an in-demand director and choreographer and ''knows'' it.
* {{Jerkass}}: Derek appears to have a reputation for being talented, but a massive jerk:
** JerkWithAHeartOfGold: YMMV, but Derek's "jerk" behavior is just managing show business. When he's speaking to Ivy as a human being (as opposed to a director), he's fairly tenderhearted and supportive. He's not a bad or uncaring person. He drives people hard (and/or manipulates them) to create the best art he can.
* LoveConfession: Acknowledges his love for Ivy at no smaller event than the Tonys.
* LoveTriangle: Attracted to both Ivy and Karen, but ends up in a full-blown romantic relationship with Ivy while settling into a friendlier muse-director relationship with Karen.
* MeanBrit: A harsh perfectionist to the point of outright cruelty towards his cast, and sometimes even his fellow creative team members.
* OnlySaneMan: Tends to think he is, given he is less emotional than his colleagues, but is a bit of a mad genius in his own way.
* {{Nepotism}}: Accepts the idea that a critic once praised him because said critic was a longtime family friend. Tom reveals that in fact the critic was sleeping with Derek's father.
* PermaStubble: Generally well-kept, but grows into a full-on BeardOfSorrow during his pre-Tonys disaster.
* WorkingWithTheEx: When his stint as director and Ivy's stint as Marilyn overlap. Also blackmailed into it with Daisy Parker.
* YourCheatingHeart: Hooks up with Rebecca Duvall while still involved with Ivy.

!Karen Cartwright (Katherine [=McPhee=])
An aspiring actress from the Midwest with little in the way of experience but a powerful voice that gains immediate attention.

* AesopAmnesia: Her fellow ensemble members point out to her that she needs to tone it down and learn to blend into a group rather than stand out. Cue musical number in which Karen is in full-on center-of-attention mode.
* ArtisticLicenseMusic: In real life, no musical theater actress would audition (for a major role, no less) with a pop song; she would likely choose a song from musical theater canon that would allow for character work similar to that of the hoped-for role.
* AudienceSurrogate: A fairly generic, nice character who serves as the audience's window into the theater world.
* BroodingBoyGentleGirl: The Gentle Girl in her her dynamic with both Derek and Jimmy.
* CountryMouse: The more experienced cast members tease her about being this, although technically she's more like a "Midwest suburban mouse".
* TheIngenue: Sweet, naive, inexperienced, yet talented.
* InSeriesNickname: Her castmates call her "Iowa," at first as a derogatory shot at her inexperience and Midwestern upbringing, later as an AffectionateNickname.
* TheMuse: Karen claims to be this for Derek in the Season 2 series premiere, following several scenes in Season 1 in which he hallucinates her as Marilyn.
* NaiveNewcomer: A Midwesterner with essentially no showbiz experience, she finds herself in ''way'' over her head and has no idea how to navigate the professional and sexual politics of the theater world.
* StrangerInAFamiliarLand: No longer feels at home when she returns to her hometown, particularly with her parents' well-intentioned but unhelpful worry over her career prospects.

!Tom Levitt (Creator/ChristianBorle)
Composer and writing partner to Julia, Tom brings stability and wit, despite his own occasional temper and failed personal life.

* BerserkButton: Don't call Tom's music "boring".
* DeadpanSnarker: Probably the snarkiest character aside from Derek.
-->'''Tom''': Art without torture. I don't think it's possible.
* HeterosexualLifePartners: With Derek, pre-series.
* IDidWhatIHadToDo: With regards to hiring Leigh Conroy- he agreed to do what was best for the production, but at the expense of what it might do to Ivy.
* InstantExpert: Subverted. When he takes over as [[spoiler: director of ''Bombshell'']], his attempts to be "nice" and open to suggestions backfire spectacularly, and he clearly struggles to maintain control and give useful notes.
* IWantMyBelovedToBeHappy: Tells Sam to take a gig touring with ''The Book of Mormon'' even though it will mean being away from him.
* LoveTriangle: A subdued version for a few episodes while he's dating John but growing closer to Sam.
* NiceGuy: Has his diva moments like the rest of the cast, but generally tries to treat everyone kindly and respectfully (except [[BerserkButton Derek]]).
* PlatonicLifePartners: With Julia.
* SecretKeeper: For Julia's affair with Michael.

!Ivy Lynn (Megan Hilty)
A longtime chorus girl and Broadway vet, Ivy is a triple threat who may have finally gotten her big break.

* AmbitionIsEvil: Initially presented as an antagonist for the simple fact that her ambitious career goals put her opposite Karen.
* AmicableExes: For the most part, [[spoiler: she and Derek]] maintain a surprisingly decent (though still complicated) relationship.
* AlphaBitch: Ivy behaves like this towards Karen by being rude to her or passive aggressively trying to get her thrown out of the workshop. She gets a little better.
* BroodingBoyGentleGirl: While not "gentle" exactly, Ivy is usually the sane voice to Derek's work-obsessed brooding.
* DependingOnTheWriter: Gets hit with this ''hard'' in Season 1. Depending on the episode, Ivy is portrayed as either a pathetic victim, a vengeful diva, or a genuinely hard-working actress. Season 2, fortunately, evens her out.
* {{Deuteragonist}}: Karen is the point-of-view character, but the story is driven almost equally by Ivy's arcs.
* DrivenToSuicide: [[spoiler: Suggested, then averted. The first season finale ends on a cliffhanger with a rejected Ivy holding a large handful of pills. She doesn't take them.]]
* DumbBlonde: Averted. Ivy is one of the most pragmatic characters in the entire show.
* EarnYourHappyEnding: And ''how''. Ivy suffers through an emotionally exhausting workshop process, an insensitive boss/boyfriend, losing two jobs in quick succession, a suicide attempt, a show in which she does well closing immediately, and turmoil with her mother. By the end of the finale, however, she has [[spoiler: reunited with Derek, is expecting a baby that she's decided she does want, and has won a Tony.]]
* FirstGirlWins: [[spoiler: Out of all the women Derek is romantically linked with, she is the one he ends up with.]]
* InadequateInheritor: Struggles with feeling unworthy to follow in the footsteps of her famous, acclaimed mother.
* MamasBabyPapasMaybe: Invoked and subverted. When [[spoiler: Ivy becomes pregnant]], Sam asks if [[spoiler: the father could be anyone but Derek]]. She immediately answers in the negative.
* MommyIssues: Her mother was (and still is) a huge Broadway star who enjoys the spotlight and can often be insensitive, leaving Ivy with no small amount of confidence issues.
* WellDoneSonGuy: A female variant. Despite her successes, Ivy's mother has a knack for making her feel incredibly inadequate, and Ivy desperately seeks her approval even while being frustrated by it.

!Eileen Rand (Creator/AnjelicaHuston)
The producer of ''Bombshell'', Eileen is passionate about the material but also trying to pull herself up professionally and personally following the nasty implosion of her marriage to her producing partner.

* BenevolentBoss: Despite being technically in charge and very no-nonsense, Eileen treats her co-workers and employees with respect.
* DeadpanSnarker: Along with the rest of the ''Bombshell'' team, has a very dry sense of humor.
* IWantMyBelovedToBeHappy: Finds herself unexpectedly on the receiving end of this trope.
* MamaBear: Do ''not'' mess with her daughter (particularly if you're said daughter's father). She's even willing to sacrifice the good of her musical if it means keeping her daughter out of the media fray.
* OnlySaneMan: As the non-creative partner, tends to be the most levelheaded and business-minded
* TeamMom: Spends a fair amount of time wrangling the rest of the creative team and trying to work out their differences.
* UptownGirl: Well-off, successful Broadway producer who falls for a rough-around-the-edges bartender.

!Sam Strickland (Leslie Odom Jr.)
Introduced a few episodes into Season 1, Sam is a member of ''Bombshell'''s ensemble and a longtime friend of Ivy's. He does his best to avoid the drama surrounding him while being a loyal and supportive friend.

* AmazinglyEmbarrassingParents: To a degree. His parents are more worried than embarrassing, but that doesn't stop them from questioning his career choice in front of his boyfriend, nor does it stop them from whooping and teasing upon seeing Tom and Sam kissing on the porch.
* BlackBestFriend: To Ivy
* {{Gayngst}}: Solidly averted. Despite his fairly traditional family and his staunch religiosity, seems to be completely comfortable in his sexuality.
* LetsWaitAWhile: Gently but firmly rebuffs Tom's initial advances when they first start dating, explaining that he wants to wait until it will really mean something.
* OnlySaneMan: Among the actors, Sam is by ''far'' the least prone to drama and the likeliest to tell it how it is.
* PutOnABus: Takes a role in a national tour early in Season 2.
* RealMenLoveJesus: To Tom's surprise, Sam reveals himself to be a Christian, and puts a hold on having sex until the two are in a real relationship.
* StraightGay: He doesn't want to have to wear a label, but his massive love for sports and lack of any stereotypical gay mannerisms make Michael Swift comment that, if he wants to get a date with anybody, he might literally have to.
* TwoferTokenMinority: Subverted, as he's both gay and black but he's also a big sports fan and a regular churchgoer, two traits not often found among actors/dancers. The actor who plays him downplays his sexuality in interviews, saying it shouldn't matter.
* WorkingWithTheEx: Briefly, in Season 2. It doesn't go well.

!Ellis Boyd
* AmbiguouslyBi: Has a girlfriend, but is perfectly willing to flirt (or more) with men to carry out his schemes. It's left ambiguous if he's just that goal-focused or if he is actually bisexual.
* ItsAllAboutMe: He honestly believes that his comment on Marilyn is what created the musical, everyone owes jobs to him and that he's key to the show. When he snaps to Eileen on his supposed skills and he should be named a producer, she fires him.
* JerkAss: Ellis, what with his constant squabbling with Julia and [[spoiler: poisoning Rebecca Duval in an attempt to put Ivy in the role of Marilyn]].
* ProfessionalButtKisser: Towards Tom, Derek, and Eileen.
* PutOnABus: Following extremely negative fan reaction, was fired at the end of Season 1 and completely written out for Season 2.
* TheScrappy: Ellis, for Julia in-universe (And for many fans as well)
* SmallNameBigEgo: Summed up when he rants to Eileen on how he's done so much and "I deserve to be named producer" when he has zero theater experience and nothing more than the lowly gopher.

!Dev Sundaram
Karen's boyfriend who works in PR for the mayor's office and has high aspirations of his own.

* ButtMonkey: His career ambitions tend to collapse more often than not, leaving him at the whims of his rivals.
* CrazyJealousGuy: Progressively gets more and more suspicious and disapproving of Karen's career, particularly her growing bond with Derek and with Rebecca Duvall.
* IJustWantMyBelovedToBeHappy: Despite his huge mistake costing him his engagement and future with Karen, he is still present at her premier in Boston, and proudly smiles watching her accomplish her life long dream.
* TheObstructiveLoveInterest: Professes support for Karen's career but tends to hinder her more often than not.

!Frank Houston (Brian D'arcy James)
Julia's husband, a former high school science teacher who took time away from his career to support Julia's- a decision not without some regrets.

* BerserkButton: The fastest way to make him angry? Bring up Julia and Michael's affair and/or how it was common knowledge among the cast and creative team.
* HollywoodToneDeaf: Frank teasingly serenades Julia in one episode, and the effort of a Tony-nominated actor to simulate "bad" singing is fairly obvious.
* HouseHusband: Stepped away from his career as a high school science teacher to take care of things while Julia worked. Eventually goes back to work partway through Season 1.
* LoveTriangle: With Julia and Michael; later revealed that Julia has emotionally felt torn between them for much longer than she let on.
* NiceGuy: All-around decent, kind, supportive husband to Julia, despite his misgivings- until he finds out [[spoiler: about her affair]]

!Michael Swift (Will Chase)
An in-demand leading man, Michael is brought on board to play Joe [=DiMaggio=] but brings more personal baggage than the others expect.

* AnguishedDeclarationOfLove: Makes a habit of these, with nearly every time he expresses his feelings for Julia being full to the brim with angst and heartache and drama.
* BackForTheFinale: After disappearing for all of Season 2, Michael reappears [[spoiler: when Julia shows up on his doorstep at the end of the finale, presumably to rekindle their relationship]] after being referenced a few times in the previous few episodes.
* TheBusCameBack: [[spoiler: Reappears in the series finale, hinting at a possible renewal of his relationship with Julia.]]
* TheOneThatGotAway: Seems to view [[spoiler: Julia]] as this, and the feeling is mutual.
* PutOnABus: For Season 2, explained by him "doing a favor" for the ''Bombshell'' team by stepping in for the out-of-town tryout but not wanting to continue with the show, for reasons personal and professional.
* RealitySubtext: InUniverse, his defense of [=DiMaggio=] as a character and a love interest for Marilyn mirrors his romantic entanglement with Julia. Carried to its logical extreme in the scene where he and Julia improv a Joe/Marilyn scene that is really about their own relationship ending.
* TenorBoy: Both InUniverse and for the show, though with considerably more moral ambiguities.
* YourCheatingHeart: Cheats on his wife [[spoiler: with Julia]]

!John Goodwin (Neal Bledsoe)
A lawyer who is set up on a blind date with Tom and quickly finds himself with a front row seat to the crazy world of theater.

* GayConservative: Tom is (comically) horrified to discover his boyfriend is a Republican.
* HelloAttorney: Tom is unenthusiastic about going out with the lawyer his mother set him up when. Once he sees him? "Yay, Mom."
* NiceGuy: Generally sweet, patient, and perfectly understanding about Tom's insane life.
* SatelliteLoveInterest: John hangs around for a few episodes, helps Leo out with his legal issues, and gets dragged along to a few events before dumping Tom over his obvious attraction to Sam. That's about it.

!Leigh Conroy (Bernadette Peters)
Ivy's mother and a stage legend- though her many awards are unlikely to include "Mother of the Year."

* ForYourOwnGood: How she justifies her constant pushing of Ivy from the time she was a little girl.
* LivingLegend: Leigh is a legendary star in the Broadway community- although her fame and success came at the expense of her relationship with Ivy.
* ParentalNeglect: Though not intentionally cruel, her ambition, sharpness, and lack of filter made her a less-than-ideal mother to an insecure young Ivy.
* RealLifeRelative: InUniverse, as the ''Bombshell'' team brings on Leigh to play Marilyn's mother, playing on the publicity of having a real mother and daughter playing Gladys and Marilyn.
* SpotlightStealingSquad: InUniverse, where her mere presence in a room is enough to draw attention away from Ivy (and anyone else, for that matter). Not that she discourages it.
* StageMom: Literally, too.

!Rebecca Duvall (Creator/UmaThurman)

A big-name Hollywood star brought on to play Marilyn in hopes of drumming up more buzz. Whether or not she's up to the task remains to be seen.

* DawsonCasting: InUniverse, the age gap between Rebecca and Marilyn does not escape attention:
-->'''Sam:''' Yeah but wasn’t Marilyn, like, 36 when she died?\\
'''Tom:''' Yes, and Rebecca is 36…ish.\\
'''Sam:''' “Ish” being the operative word.
* InformedAbility: InUniverse, as the creative team is assured over and over again that Rebecca can sing, and on the first day of rehearsal, the reality is... somewhat different.
* IronyAsSheIsCast: Again, InUniverse instance, where Rebecca is hired and quickly proves to be a ''complete'' mismatch for the emotionally complex, big-voiced role of Marilyn.
* JerkWithAHeartOfGold: Has her diva moments, but is willing to make compromises with the creative staff to ensure "Bombshells" success, and becomes both a friend and mentor figure to Karen.
* PutOnABus: Quickly exits ''Bombshell'' after bad public response, [[spoiler: and an attempt on her life]] and the series at the end of Season 1.
* VocalRangeExceeded: Try as she might, Rebecca ''cannot'' handle some of the big songs Tom and Julia have written. However, she at least is aware of her own limits: she hires a vocal coach, suggests lowering the keys of some of the songs, and is willing (at least initially) to allow some of the Marilyn material to be given to the "shadow selves."

[[folder:Characters Introduced in Season 2]]
!Jimmy Collins (Jeremy Jordan)
A bartender and composer whose path crosses with Karen's, Jimmy's gift for music and harsh demeanor cover a troubled past which keeps coming back to haunt him, no matter how hard he tries.

* AesopAmnesia: As many times as he is called out on his Divaish attitude, and ''(half-heartedly)'' apologizes for it, it's almost assured that the next episode he will revert back to his {{Jerkass}} ways only to be called out again.
* DarkAndTroubledPast: Comes from an apparently bad family life and at one point [[spoiler: was dealing drugs and not calling for help for overdosed addicts]]. It got bad enough that, when he got out with Kyle's help, he even [[spoiler: changed his name.]]
* FriendsAreChosenFamilyArent: Comes from an abusive background and is at his worst when [[spoiler: his lowlife brother]] shows up, but is capable of being quite warm and funny when around others, particularly Kyle, whom he calls his "real brother."
* HairTriggerTemper: His temper comes and goes, but when he is in a mood, it only takes the smallest thing to set him on a rant.
* ItsAllAboutMe: Just can't get it through his head that their are other talented dreamers trying to make it on Broadway just like him. Unfortunately, all his whining and complaining get him exactly what he wants.
* {{Jerkass}}: Gets angry at the smallest provocation, reacts to disappointment by sulking and snarking bitterly, and is generally unpleasant to everyone a good chunk of the time.
* KarmaHoudini: Zigzagged, his whining and complaining intially get him everything he wants, a producer for "Hitlist," but after the entire team and crew get sick of his diva moments, they attempt to cut him from the production, [[spoiler: until Kyle's death makes him crucial to finishing the product, and later formal charges of manslaughter, for his part in the death of the girl that overdosed due to his negligence, are filed against them.]] By this point however he is actively trying, to varying degrees of success, to be a better person, for Karen's [[spoiler: but most importantly to honor Kyle's memory, willingly accepting the charges and goes to jail as pennace for his DarkAndTroubledPast.]]
* LoveRedeems: A platonic version: although he falls for Karen, it is his brotherly love for Kyle [[spoiler: and guilt over indirectly causing Kyle's death]] that usually brings him out of {{Jerkass}} mode.
* ManlyTears: After [[spoiler: Kyle dies.]]
* SecondLove: For [[spoiler: Karen, following Dev's departure]]
* TheStoner: Openly admits to doing a variety of drugs from time to time. [[spoiler: At one point in his past, he was a dealer as well as having his own drug problem.]]
* TookALevelInKindness: Following [[spoiler: Kyle's death]], Jimmy becomes decidedly mellower and (with a few exceptions) tries to be a nicer person out of respect.
* WhatTheHellHero: After his behavior starts to hinder ''Hit List,'' the cast calls him out, particularly when said actions almost lead to Karen being seriously hurt, and eventually the staff come to the agreement [[spoiler: to kick him off the production staff, leaving Kyle to deliver the news.]]
** Julia calls him out on his horrid behavior towards her after she points out she was doing him a favor in assisting him with ''Hit List'', out of her genuine affection for [[spoiler: now deceased]] Kyle, even at the hindrance of ''Bombshell''.

!Kyle Bishop (Andy Mientus)
Jimmy's best friend and coworker, Kyle is an aspiring bookwriter with a deep passion for theater whose dreams may exceed his talents, but whose drive keeps his and Jimmy's work moving forward.

* {{Adorkable}}: Particularly in his awkward early attempts at flirting and whenever he meets someone famous.
* AllLoveIsUnrequited: In the earlier episodes of Season 2, he has a crush on Jimmy who has a crush on Karen who also has some tension with Derek... Eventually he meets Blake and this goes away.
* AscendedFanboy: Has loved the theater, particularly the works of Houston and Levitt, his whole life and now finds himself right in the middle of it all, as well as his talent being recognized by his Idol Julia, and his crush on Tom being briefly reciprocated.
* {{Expy}}: Of Jonathan Larson, [[spoiler: all the way down to him dying a week before ''Hit List'' premiers on Broadway.]]
* TheKnightsWhoSaySquee: Even once ''Hit List'' becomes a realized production, he consistently fanboys over his theatrical idols.
* MoralityPet: Does all he can to keep Jimmy in line.
* YourCheatingHeart: [[spoiler: With his celebrity crush, Tom Levitt.]]

!Ana Vargas (Krysta Rodriguez)
New roommate and old friend to Karen, Ana is an actress who is tired of almosts and ready to shine.

* AlwaysSomeoneBetter: Often feels overshadowed, particularly by Karen.
* RememberTheNewGuy: Has apparently been friends with Karen for years, but is never mentioned or seen until Season 2.

!Scott Nichols (Creator/JesseLMartin)
The artistic director of Manhattan Theatre Workshop and a former friend of Julia's from grad school. Scott takes an interest in ''Hit List'' and pushes the young team to take the next steps.

* FictionalCounterpart: Runs the Manhattan Theatre Workshop, ''Smash'''s counterpart to the real-life New York Theatre Workshop.
* NewOldFlame: He and Julia had some romantic tension in their grad school days, although it never went anywhere because of her relationship with Frank and her professional betrayal of him.

!Blake (Daniel Abeles)
A lighting designer for ''Hit List''

* SatelliteLoveInterest: All we ever really know about him is that he's a lighting designer, he can stand up to Derek, and he really likes Kyle.

!Patrick Dillon (Luke Macfarlane)
A prominent member of the theatrical community and a Tony Awards voter on whose bad side Tom keeps inadvertently getting.

* LastEpisodeNewCharacter: Is built up as a potential love interest for Tom, despite being introduced in the series Finale.
* TransparentCloset: Apparently ''everyone'' knows he's gay, even though he insists otherwise. Eileen even comments that he's the reason they invented the term "glass closet."
