Adaptational Heroism: While Seymour is mostly the same character he was in the stage version, he is given a much more sympathetic light in the film version by having most of his Moral Event Horizon moments cut down or downplayed.
Catapult Nightmare: Seymour has one in the extended "Meek Shall Inherit" sequence, where he sees Mushnik's painting drip with blood and himself turned into a plant monster.
Catch Phrase: "I didnít mean it " whenever he makes a mistake in the original movie.
Corrupt the Cutie: He agrees to feed people to Audrey II to keep it alive and win Audrey's affections. However, after he feeds Audrey and realizes what Audrey II is planning, he decides to try destroying it. He fails in the plays, but succeeds in the theatrical cut of the movie.
Defeat by Modesty: In both versions of the film, Audrey II thwarts Seymour's attempt to axe it by pantsing him, prompting Seymour to drop the ax and duck behind a counter.
Disappeared Dad: In the original movie, his father left because of his motherís terrible cooking.
Driven to Suicide: In the original film, after feeding Audrey to the plant, Seymour goes up to the roof to shoot himself in the head. Then Paul Dooley shows up and Seymour learns what Audrey II has planned.
Humiliation Conga: The uncut version of "Mean Green Mother" has the plant gloating about how he has destroyed Seymour's life and will soon do the same to people all over the world, easily thwarting his attempts to kill him, robbing him of his last dignity by stealing his pants, destroying his home by pulling it down over him, and eventually eating him up.
Karma Houdini: Seymour killed two people (he let Orin die despite making it clear that he could have helped him and he backed Mushnik into the plant) and considered going even further (he signed the contracts in "The Meek Shall Inherit", implicitly agreeing to kill others in the future. This is made clearer in the play where the song is extended, but the actions remain the same in the film.) but in the theatrical cut, he gets away with absolutely no punishment whatsoever-Audrey likely never even learns that he is a murderer.
It can be argued that Seymour finally standing up to and destroying the plant thus preventing the destruction of the human race pretty much makes up for the world being less one sadistic dentist (which WASN'T his fault, despite intentions to the contrary) and one greedy, albeit somewhat kind, shopkeep (which may not have been entirely on purpose whatever the plant said). Both deaths are made a lot more ambiguous in the film than the play, and can be interpreted as due to Seymour's actions or not.
The Director's Cut makes it pretty clear that he didn't get away with anything, even if you don't count his death. Orin and Mushnik died only because Seymour doesn't prevent their deaths, and they both would have harmed him (Orin with dental sadism, Mushnik through blackmail) even if he had saved them. Audrey, on the other hand, he consciously fed to the plant, even if it was at her own selfless request. If he hadn't done it, Audrey II might not have been strong enough to tear down the building and eat Seymour whole.
In a deleted scene, Seymour during the "The Meek Shall Inherit" scene does grab an axe to destroy Audrey II, but the thought of losing Audrey stays his hand.
Laser-Guided Karma: In the original 1960 film, Seymour is one of the buds when Audrey Jr. blooms, along with the other people he fed to the plant.
My Beloved Smother: In the original movie, heís stuck looking after a bedridden, hypochondriac mother who doesnít want him to marry Audrey.
My God, What Have I Done?: The film gradually leads Seymour to this. He's horrified that he chopped up Scrivello and he led his boss into Audrey II's jaws. Eventually, he realizes that he's gone too far and doesn't want to continue with what he's been doing.
Nice Guy: Once you get past the "grows a giant man-eating plant that needs blood to stay alive" thing.
Nice Job Breaking It, Hero!: Seymour gets a lot of these moments, but the one that takes the cake is when Seymour willingly feeds Audrey to the Audrey II. In the scene just before, the plant had to brace itself (and expend a great deal of effort) just to move its pot a few feet to reach the pay phone. After eating Audrey, it becomes fully mobile and gains enough strength to destroy the shop and devour Seymour.
Audrey II also rubs it in Seymour's face that he helped bring his plan to fruition.
Seymour: We're not talking about one hungry plant here, we talking about world conquest!
Audrey II:(practically giggling) And I wanna thank YOU!
Senseless Sacrifice: In all versions save the 1986 film, Seymour tries to kill the plant by letting himself get eaten (or charging into the plants maw) with an axe to hack from the inside. It doesn't work.
All Girls Want Bad Boys: Averted. Even though she dislikes being in a relationship with Orin, she just can't break it off, because she fears his reaction to the breakup. She also states she doesn't deserve a good relationship.
Dramatic Irony: After the flower shop's first successful day of business, Mushnik tells the leaving customers to come again to see the Audrey II as it was going to get bigger and more amazing. He didn't know how right he was.
Jerk with a Heart of Jerk: He still treats Seymour like crap and admits he never liked him to begin with in the play-only "Mushnik and Son," even after Seymour is solely responsible for saving the flower shop, and tries to get rid of Seymour so he can feed Audrey II himself. He does, but not in the way he thought. At least in the movie — in the play, Mushnik has good reason to believe Seymour killed Orin and is simply doing his duty as a citizen by telling the police what he knows, and he gives Seymour the opportunity to come with him and defend himself, in case it really isn't what it looks like. Seymour tricks him into getting too close to the plant, purely to save his own ass.
Award Bait Song: "Mean Green Mother From Outer Space" is not present in the stage version, although it has been added in some revivals. It was added to the screenplay so the film could receive an Oscar nomination for "Best Original Song." It lost, sadly. (It should be noted that "Mean Green Mother From Outer Space" is definitely not your typical Award Bait Song. It was based on a song for the original stage version, "Bad", that got dropped.)
Single Specimen Species: In the original, he is the only one of his kind in existence as he was a crossbreed between a butterwort and a Venus flytrap. In the musical, heís an alien so there are probably more of them in space but the only other one we see is in Seymourís flower bed after the original Audrey II is killed.
The play and the original ending have them breeding and taking over America.
Enfante Terrible/Creepy Child: "When I was young and just a bad little kid, my Momma noticed funny things I did, like shooting puppies with a BB gun, I'd poison guppies and when I was done, I'd find a pussy cat and bash it's head, that's when my Momma said..."
Kick the Dog: Itís implied that he literally did this as a child but he twists the head off a baby doll that a little girl is holding as he walks into his practice.
Heel Realization: Orin seems to experience one as he lays dying. When told he's being murdered because of "What you did to her", he first asks, confused, "Her who?" After a moment to dwell, he remarks in a sad voice, "Oh.... Her" before his breathing stops.
Pet the Dog: When he first meets Seymour, he bullies him a bit, however in two instances he was nice to him in his own depraved way. Before knowing who he is, he offers him some Nitrous Oxide, something he doesn't even give his patients. When he does know him he acts starstruck and is genuinely amazed that Seymour was able to have a plant as big as Audrey 2.
They Wasted a Perfectly Good Character: Heís a dentist who gets off on giving painful treatments. The first movie kills him just before heís due to see a patient with a sexual fetish for painful dentistry. Luckily they meet each other in the musical.
What the Hell, Hero?: He has this attitude towards Seymour in the musical. Rather than help him get the mask, Seymour decides to let Orin suffocate from the gas. This line of dialogue certainly warrants this trope:
Orin: Hey, Seymour, give me a hand, will ya?
Orin: ...Well? He says, "well"?
Would Hit a Girl: Aside from beating Audrey, he casually punches a dental nurse on his way into work.
Crystal, Ronette, and Chiffon
Played By: No one in 1960 / Tichina Arnold, Michelle Weeks, and Tisha Campbell-Martin
The Faceless: In the final scene, the camera moves down to the new Audrey plant before we see Chiffon's face, because they had to replace the actress.
Fake Shemp: One of the Greek Chorus Girls wasn't available to shoot the Focus Group Ending, thus the camera abruptly panning down after the other two come into frame.
Greek Chorus: An interesting example, going back and forth between standing outside the action and commenting on it to the audience, and interacting with the other cast members using no special out-of-character knowledge. You can keep track by the costumes; when they're characters the girls wear worn-down clothing appropriate to residents of Skid Row, and when they're a Greek Chorus they've changed into sparkly dresses.
Jerks With Hearts of Gold: Their Skid Row selves (ie, when they're not being the Greek chorus) show signs of this. They're sassy, snarky, pushy, and tease Seymour and Audrey a bit... but they also encourage Audrey to get together with Seymour, tell her she needs to work on her self-image problems, and chew Orin out for his abuse towards Audrey when he comes by looking for her.
Freudian Excuse: His masochism may or may not have been caused by his child dentist's habit of giving him candy bars after painful procedures.
Jerk with a Heart of Gold: While he is a Masochist, he understands not everyone is as enthusiastic to pain as he is. And since he opted for the most painful procedure on himself, he honestly considers the poor kid with the wired jaw to be considered lucky.
