When the Warriors first leave the gunfight in the Bronx, we see them walking in the rain, completely soaked. A short while later, they're back on the train with dry hair and clothes.
When two of the scattered groups of Warriors meet at Union Square, Snow and Cowboy tell Cochise, Vermin, and Rembrandt that Ajax got arrested and they don't know where Swan is. Nobody asks about Fox, although none of them could have known what happened to him, as Mercy was the only one who saw a cop grab Fox, and Swan was the only one she'd told about it.
When walking, the girl is wearing high-heel sandals. However when she is running with the Warriors as they are chased by the cops in the subway station, she is wearing "practical" shoes.
A cut disappears and re-appears in subsequent shots under the
eye of the Orphan Leader when Swan and Fox are talking to him.
Near the end of the opening title scene, Ajax says, "Maybe we'll get to bust a few heads along the way." Cut to Cleon saying, "You just soldier and keep your mouth shut," then cut back to a quiet Ajax. However, in the frontal shots of Ajax, it is not Cleon he is speaking to, it appears to be Thomas Waites as Fox. The skin looks white and a chain on the back of his neck is visible, as well as his curly hair. Fox wears a chain with a cross that is visible in several shots. Cleon wears a camouflaged-colored cloth that covers his head and neck.
The end credits have some mistakes in the cast section. Masai was actually played by Edward Sewer (incorrectly credited as Gramercy Riff gang member), not Dennis Gregory; Leon Delaney was the Baseball Fury gang member in the movie (not Punk); and Rob Ryder played both Baseball Fury and Punk gang members.
The song Nowhere to Run in the end credits is misspelled, with Nowhere spelled as two words (No Where) on the Director's Cut home video version.
In the end credits for the song Love is a Fire, Genya Ravan's last name is misspelled as Raven (Director's Cut home video version.)
At the beginning of the film, the Warriors are seen taking the B train at night, even though it does not run at night.
When the Lizzies shoot at the various Warriors, not one of them gets hit, despite the fact that the gun should have at least clipped one of them and maybe all of them.
Mercy insults the Orphans' leader for allowing the Warriors to flash their colors in Orphan turf. Why would this pose a problem if a city-wide gang truce were in effect? Gangs from all over the city flashed their colors in the Bronx when attending Cyrus' meeting as a condition of the truce. It was never established that the truce was called off upon Cyrus' death. Fox and Swan could have mentioned this to the Orphans in their parlay. And if the Orphans sought to be "with it", they could certainly honor the truce. [It is repeatedly stated that the Orphans are so far down the ladder that they are not in the loose organization of gangs the Riffs have set up. They did not know of Cyrus' meeting or that he had been killed and that the Warriors were suspected of killing him. Thus it is entirely possible they had no idea there was a truce going on.]
In the graveyard near the beginning, when the Warriors are discussing returning home, Vermin complains, "Coney Island must be 50 to a hundred miles from here." Coney Island is actually less than 25 miles from Van Cortlandt Park by foot. While the character may either be exaggerating or genuinely ignorant of the exact distance, for a native of the city this is still a pretty wild overestimate. This is clearly a deliberate exaggeration to show the ignorance of the character of Vermin.
The opening sequence uses "millenniums" instead of the more traditional "millennia." While it may bother Latin aficionados, both words are listed as acceptable in modern English dictionaries.
After Cyrus is shot when he is falling off of the platform, the stunt double who falls is white. This is Craig R. Baxley, the only stunt double who was capable of doing the stunt.
Fox is thrown onto the tracks and presumably killed when the train comes at him in the 96th Street station. When Swan and Mercy come back together, they go down to the tracks at the 96th Street station. There would be police and other crews all over the station had someone been killed on the tracks just a short while ago, but the station is empty except for one lone passenger.
After the fight with the Furies, Swan makes it back to the 96th Street Station and meets Mercy again. She offers to show him how to get to Union Square, and they both go through the turnstile without either one of them putting in a token.
When Luther taunts the Warriors with the bottles, the hearse is parked alongside the ramp, which runs from the boardwalk down to the street. When the hearse is shown from under the boardwalk, the ramp slants down to the right, but in the close-up of Luther, the ramp slants down to the left, plus the whole ramp is about four or five feet lower.
When the Warriors are on the Orphans' turf and the Orphans run for backup, Swan is talking to Mercy. From behind Swan, there are a few of the Orphans visible before they all come to attack.
In the Warriors' showdown with the subway gang the Punks, the fight takes place in a station bathroom containing a long row of wooden enclosing stalls. At several points during the fight scene, members of the Punks are thrown into the stall walls or through doors. Looking at the destruction of the structures, it's obvious that the wood was all pre-cut to break away easily and completely.
Stuntmen were often used throughout the production's fight sequences. In the subway bathroom fight, a brief pause at the moment when Vermin is thrown into the mirrors above the sinks will clearly reveal a blonde-haired stuntman performing the action.
David Patrick Kelly is credited as "Luther;" however, the character is never addressed by name anywhere in the film.
Luther drops the gun after Swan throws the knife into his wrist. Swan then approaches Luther as he kneels wounded in the sand but doesn't pick up the gun. Logically, it would make sense to grab the gun so no other member of the Rogues could use it.
When the Warriors face off with the roller-skating gang in the subway, there is an 'Amusement Arcade' with various pinball machines, etc., out in the public area, open and unprotected in the middle of the night. Any amusements in the New York City subway left unattended overnight would be immediately destroyed and/or stolen, especially in the 1970s.
When Ajax gets handcuffed to the bench in the park, he starts to curse at the woman who cuffed him. At one point he shouts, "You lousy bitch!" but if you watch his face, he's clearly not saying it.
Mercy's lips don't move when she shouts, "Swan!" as he throws his switchblade into Luther's forearm at the beach.
After Swan refuses to remove his colors, the head Orphan snaps his fingers to call his soldiers, but the snap is heard after it actually happens.
When the Baseball Furies are chasing the Warriors through the park, Swan says: "Snow, with me." When he says "... with me", his lips move differently from the words.
In the scene in the park with the female officer arresting Ajax, the patrol car pulls up and several officers get out. Ajax kicks the one officer but is taken down by the second officer with a nightstick to the stomach. In a subsequent shot showing that officer, the image is mirrored. You can see that the badge in on the right side of the officer and the patrol car is facing the other way.
Before Luther (David Patrick Kelly) starts chanting, "Warriors, come out to play-yay," you can hear the director say, "David... action," off-screen.
When the Warriors meet up at Union Square and go to look for Swan, as they're walking away, a cameraman's foot is visible sticking out from behind one of the pillars.
On the subway, while the Warriors are talking about "stealing it all", a cameraman is visible in the reflection in the window.
In the very last shot of the conclave, just before switching to the graveyard scene, massive equipment is visible to the left of the speaker's platform, including a camera truck with its crane lifted, a cluster of floodlights, and several crew members.
At 15:09 of the DVD, as the gangs are all trying to escape the area from the police raid, a film crew member with a yellowish shirt is visible with a clearly labeled Panavision camera for a few seconds on the middle far right of the screen.
After the Warriors meet and then leave Mercy in the Bronx, she walks the streets looking for them. She passes a black street sign with white lettering, indicating she is really in Brooklyn (where the scene was filmed), not the Bronx. In the '70s, the street signs were color-coded: Brooklyn's was black with white letters and numbers, and the Bronx's was blue with white letters and numbers. Manhattan's was yellow with black lettering and those are in many shots.
In the 96th Street and Union Square subway stations, a lot of the names say Hoyt on the tile walls.
The 96th Street entrance, where the Warriors meet the Baseball Furies, is actually the 72nd and Broadway entrance. The Gray's Papaya hot dog stand visible in the scenes has been there for over 35 years.
As the Warriors escape from the Gun Hill gang in the Bronx by jumping turnstiles, the token booth behind them shows Eastern Parkway, a station in Brooklyn.
Supposedly in the Bronx, the gang boards a Chambers Street - Metropolitan Avenue train, which would not go to the Bronx.
When Masai talks to the Riffs about looking for the Warriors, the boom mic is reflected in his oversized aviator's glasses.
When the new leader of The Riffs asks, "Who are the Warriors?" after the old leader Cyrus is shot, none of the gang answers, as if they all know nothing about them at all - but earlier, Cleon says Cyrus sent an 'emissary' to tell the Warriors about the meeting. So therefore, the Riffs must have known about the Warriors to do that; certainly, that emissary would still have information about them even if Cyrus is now dead.
