Audio problem: In the famous "beer bottle" scene where the gang leader of the Rogues Luther has three beer bottles on his fingers, if you listen very carefully you can hear the director shout to the actor David Patrick Kelly "David, action" just before Luther starts to sing "Warriors, come out to play."
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: 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.
Continuity mistake: At the end of the movie when The Warriors are back home in Coney Island and ready to confront the gang that set them up, you can see the rides, boardwalk, surrounding apartments in the background. However when they take the gang down to the beach all of the background scenery that definitely would still be visible disappears. There is no way they are still on the beach in Coney Island.
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.
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: At the beginning when Ajax says to Cleon, "I wouldn't mind busting a few heads", Cleon is wearing a head veil (when seen from the back). But when the camera turns to Cleon to see him respond with something like, "You just keep your head down", the veil is gone.

Visible crew/equipment: When the leader of the Riffs' finds out it wasn't the Warriors who killed Cyrus there is a focused shot on his face and his sunglasses reflect a crewmember wearing a white T-shirt next to what looks like a camera. It has to be a crewmember as no-one in that scene is wearing a white T-shirt.
