Continuity mistake: At the subway when Mercy and Fox were running down the stairs from the cops, they showed a back shot of Mercy and it was clearly another woman. Her hair was about shoulder length and straight. Mercy's hair is longer, and curly.
Factual error: In the scene where the Warriors are hiding from the Turnbull A.C.'s under the elevated subway they look up at the train that is approaching the station. The train is marked as a "J" train. At that point they are still in the Bronx. The "J" train never runs in the Bronx.
Audio problem: In the famous "beer bottle" scene where the gang leader of the Rogues has three beer bottles on his fingers, if you listen very carefully you can hear the director shout "action" just before the actor starts to sing "warriors, come out to play."
Continuity mistake: After Ajax is arrested Swan goes to the station with "tough chick", the first time you see the train platform it's empty but a few seconds later a man has appeared from nowhere, then a policeman sees Swan and chases him and the man has once again vanished.
Revealing mistake: As the gang is being chased through the "96th Street Station", you can see the true station name "Hoyt" (as in Hoyt-Schermerhorn Sts. Station) on the outer station wall.
Audio problem: When Ajax is at the park handcuffed to the bench, he calls the woman a stupid bitch, but his mouth never moves.
Continuity mistake: When Vermin says to the woman,"Looks like you're the winner." they both sit down and start to kiss, but in the next shot when Rembrandt and Cochese start talking, you can clearly see Vermin walking by talking to the woman.
Visible crew/equipment: When The Warriors are running down the centre of the street (heading to the train station) as they are chased by the Turnbull AC's in their bus, on the left of this shot you can briefly see two crew members wearing yellow jackets standing next to some lighting equipment for the scene.
Continuity mistake: When Cyrus is giving his speech his shirt and robe are quite open (open enough to see a necklace), but when he's shot his clothes have buttoned themselves.
Continuity mistake: In the graveyard scene, after the meeting, Rembrandt is shown at the top of this statue looking for the train station. In the next shot with Swan, in the background Rembrandt is seen still climbing up the statue.
Deliberate mistake: In the scene where the Punks follow the Warriors into the bathroom, Rembrandt sprays the head punk with his red spray paint. However, the spray coming out of the can is clear, not red.
Continuity mistake: When the Warriors are back home and they step off the train, the woman who is with Swan has a pink top on and it is really dirty on the front, but when they go and find some weapons in the abandoned warehouse she has only got a small mark on the front the size of a hand, as she did earlier on in the film.
Continuity mistake: When Mercy asks Swan "you gonna jump me?", the Orphans can be seen standing in the background, even though they haven't arrived on the scene yet.
Continuity mistake: The girl with the Warriors started the film with red high heels that had a single strap over her toes, but when we see her feet on the subway and for the rest of the film, her shoes are black with a split strap.
Visible crew/equipment: In the scene right before the Warriors do battle with the Punks, they meet on the landing, and when they are about to go off you can see a blue sneaker and pant leg next to the pillar on the right side.
Revealing mistake: When Ajax is handcuffed to the park bench and a cop punches him in the stomach with his nightstick, look at the police car behind the cop as he straightens up. The writing on the side of the car is backwards, indicating that the film was flipped to reverse left and right.
Continuity mistake: Swan tears a piece of the girl's skirt to make the fuse for the Molotov Cocktail, but her skirt is never shown to have a tear in it after that scene.
Continuity mistake: In the Coney Island scene near the end of the movie, where the car that The Rogues are tailing The Warriors in stops, in the background shot you can see that the elevated boardwalk adjacent to the car is located about the same level as the roof of the car, and is ascending upwards towards the front of the car. In the next scene with a closeup of Luther clinking the bottles in his hand, the boardwalk is all of a sudden located much lower at the car seat level and is now descending downwards towards the front of the car.
Continuity mistake: In the subway station, when the Turnbull A.C.'s recognize the Warriors, they turn the bus around and begin a fierce chase. The distance shots of them chasing the Warriors do not match up. Several times the AC's appear to gain on the Warriors, and a few other times the Warriors are way ahead of the AC's just prior to escaping up the subway stairs.
