* ActingForTwo:
** Billy West as Bugs Bunny and Elmer Fudd.
** Dee Bradley Baker as Daffy Duck, Tasmanian Devil and Toro.
** Bob Bergen as Marvin the Martian, Porky Pig, Tweety Bird, Barnyard Dawg, Hubie and Bertie.
** Bill Farmer as Foghorn Leghorn, Yosemite Sam and Sylvester the Cat.
** Colleen Wainwright as Sniffles and Naut.
* AllStarCast: An odd case.
** UsefulNotes/MichaelJordan and a bunch of other basketball stars working with WesternAnimation/BugsBunny and a bunch of other WesternAnimation/LooneyTunes. Yeah.
** The Looney Tunes voice cast included several of the leading Los Angeles VA's of the time, headlined with Creator/BillyWest and featuring Creator/DeeBradleyBaker, Creator/BobBergen, Creator/BillFarmer, and Creator/KathSoucie, with CelebrityVoiceActor Creator/DannyDevito and Creator/JuneForay reprising as Granny. (Producer Creator/IvanReitman attempted to assemble a cast that would outdo Creator/MelBlanc.)
* BillingDisplacement: The soundtrack features it in a way. The title track "Space Jam" is only the third of the album, behind "Fly Like An Eagle" and Coolio's "The Winner".
* BreakawayPopHit: "I Believe I Can Fly" by Music/RKelly, [[Music/SteveMillerBand Steve Miller]]'s "Fly Like an Eagle" as performed by Music/{{Seal}}, and "For You, I Will" by Monica. Also "I Turn To You" by All 4 One... only after it was covered by Music/ChristinaAguilera. (All 4 One wanted to release it as a single, but the label had felt they had already done enough with the soundtrack)
* TheCastShowoff: Not in the movie itself, but Creator/BillyWest, who voices Bugs and Elmer, as well as Creator/BobBergen voicing Porky and Creator/DeeBradleyBaker as Daffy, along with other characters performing a rap song on the soundtrack called "Buggin'" [[https://www.huffingtonpost.com/rap-genius/the-space-jam-soundtrack-_b_1659243.html (written by none other than]] Music/JayZ), which is all him singing to himself in his Looney Tunes voices.
* CreatorBacklash:
** Joe Pytka wasn't happy that the original ending of the film was dropped and replaced in the final cut.
** The other NBA stars featured weren't so kind to the film [[https://www.youtube.com/watch?v=LHE7vAxVYG8 if this video is anything to go by]].
** This is averted with the staff of Creator/{{Cinesite}} (who handled the film's CGI and VFX work), who openly enjoyed working on the film and acknowledge it in retrospectives.
* CrossDressingVoices: The Nerdlucks are all voiced by women. The Monstars aren’t.
* DirectedByCastMember:
** The Latin American Spanish dub was directed by Francisco Colmenero, who voiced a golfer playing with Michael Jordan as well as Daffy Duck (Pato Lucas in the dub).
** The Brazilian dub was directed by Creator/IsaacBardavid (best known as Wolverine and Skeletor), who voiced Monstar Bang.
* DisownedAdaptation: Creator/ChuckJones already wasn't fond of Looney Tunes work made without his or any other member of Termite Terrace's supervision, but he was ''especially'' vocal about his disdain for this movie. He felt the plot was too shallow for a 90-minute feature. He argued it was completely out of character for Bugs to be requesting assistance against the Monstars, saying that Bugs would take them out by himself in only seven minutes. He particularly took offense at the inclusion of ToiletHumor, paying special notice to Porky's "I think I wet myself" line. Reportedly, he got so worked up over the movie during its opening party that he had to be removed from the premises.
* EditedForSyndication: Bugs' response to Daffy's team name suggestion of "The Ducks" ("What kinda Mickey Mouse organization would call their team 'The Ducks'?") is muted on (the Creator/{{Disney}}[=-owned=]) Creator/{{Freeform}} airings.
* FirstAppearance: Of WesternAnimation/LolaBunny.
* HeAlsoDid: Korey Coleman, founder of the award-winning animated movie review site ''WebAnimation/{{Spill}}'', was an assistant animator for ''Space Jam''; he animated Tweety's shadows.
* HostilityOnTheSet: According to [[https://www.youtube.com/watch?v=DVEy4ksQ90E&t=635s this interview with animator Dave Spafford]] he didn't like working on the film or working with Joe Pytka as well as using (in his words) "the modern Creator/ChuckJones shit".
* KidsMealToy: UsefulNotes/McDonalds released a set of eight statues that could connect to each other in their Happy Meals. Bugs' toy was re-issued for the 2019 retro line.
* TheOtherDarrin:
** The French dub of this movie hired new voice actors for each Looney Tunes, save for Albert Augier as Elmer Fudd. Unfortunately, he was also replaced when the old cartoons were redubbed.
** Several voice actors for the Looney Tunes were replaced in this movie, some going on to take over their roles later
*** Creator/BillyWest replaces Creator/GregBurson as Bugs Bunny and Elmer Fudd (except for one scene mentioned below voiced by Burson), going on to become their go to voices from here on until 2003 and 2015 respectively.
*** Creator/DeeBradleyBaker replaces Creator/JoeAlaskey and Jim Cummings as Daffy Duck and Taz.
*** Creator/BobBergen replaces Creator/JoeAlaskey as Marvin the Martian.
*** Creator/BillFarmer replaces Creator/JoeAlaskey and Creator/MauriceLaMarche as Sylvester and Yosemite Sam.
*** Creator/MauriceLaMarche replaces Creator/GregBurson as Pepe Le Pew.
* TheOtherMarty: For reasons unknown, Creator/GregBurson recorded dialogue for the film that remained in the final cut even after the characters he played were recast. His voice is heard as Elmer Fudd in the scene where the Tunes are discussing which contest to challenge the Nerdlucks, and almost all of Foghorn Leghorn's dialogue is his (Bill Farmer, the actor credited, has only one audible line in the film).
* PlayingAgainstType: Creator/WayneKnight as a well-meaning yet bumbling goofball, as opposed to the FourEyesZeroSoul FatBastard type that he became famous for in ''Series/{{Seinfeld}}'' and ''Film/JurassicPark''.
* RealitySubtext: Michael Jordan did indeed return to basketball after a stint at baseball (where he was set to retire into at the time) and led the Chicago Bulls to victory on his first game since retiring! In reality, there were ''sliiiiiiightly'' fewer Tunes and aliens involved.
* StillbornFranchise:
** A sequel was planned as early as 1997. As development began, ''Space Jam 2'' was going to involve a new basketball competition between the Looney Tunes and a new villain named Berserk-O!. Due to Michael Jordan's contract not agreeing to a sequel (despite a producer lying to design artists by claiming that Jordan had signed on in order to keep development going), Warner Bros. eventually canceled plans for a direct sequel with Jordan, and eventually cast UsefulNotes/LeBronJames in the lead role for a follow-up, ''Film/SpaceJamANewLegacy'', released in 2021.
** Various other ideas for the sequel were considered, planned, and almost entered production. These include ''Spy Jam'' with Creator/JackieChan ([[Film/LooneyTunesBackInAction which became its own separate movie]]), ''Race Jam'' with Jeff Gordon, a different film with Tiger Woods in the leading role (''Golf Jam'' possibly), and ''Skate Jam'' with Tony Hawk (this almost entered production), but were never finalized for various reasons.
* SwanSong: The Latin American Spanish dub of ''Space Jam'' was Luis Puente's final film before he died on November 2, 1996, eight days before the film's release.
