Dawson Casting: With the exception of Rembrandt, the gang all look like they're in their mid-twenties, but Fox mentions that they have a youth worker. Swan and Mercy are also compared to a group of kids coming from prom. These suggest that the gang is supposed to be in their teens.
Dueling Movies: Released the same year as The Wanderers with both films sparking discussion about youth gangs. The studios raced to beat each other to the punch, but The Warriors came out first and had the more lasting impact.
The Other Darrin: While this is averted for the most part, Luther, Rembrandt, Vermin and Cyrus (except for his iconic speech) were all recast for the video game
Throw It In: David Patrick Kelly ad-libbed the iconic scene in which he clanks the empty bottles together and calls out a challenge to the Warriors. Ajax's James Remar also ad-libbed his line, "I'm gonna shove that bat up your ass and turn you into a Popsicle!"
An opening narration was planned, voiced by Orson Welles. It's included on the director's cut DVD, along with comic book-style transitions between scenes.
If Hill wouldn't have been able to make this movie, his backup plan was to do a western film called Last Gun.
Originally it was Fox who was supposed to be the sympathetic character whom Mercy goes with in the end. The director and the actor playing Fox had a falling out, so he gets hit by a train. Furthermore, Vermin was supposed to die at the hands of the Lizzies, but his actor threw enough humor to make him memorable that the director decided not to kill him. Swan was supposed to be kidnapped by a gang with a penchant for anal rape, but escape and return for the final showdown.
Tony Danza was set to play a role, but chose to star on the sitcom Taxi, instead.
Orignally, the film was a going to have an all black and Hispanic cast much like the book.
