The number of men attacking Priest in the final fight scene varies from shot to shot, though, from the angles used, there should be a consistent number.
The foot chase at the beginning seems to be shot out of order. The junkie either has his hat on or he's holding it.
The gun Scatter pulls on Eddie changes between shots.
The gun Scatter pulls on Eddie changes drastically (and hilariously) between shots. At first Scatter pulls a silver .22 pistol and a minute later he hands a white handled revolver to Eddie.
When Priest fights "The Man"'s henchmen at the end, the man who is body slammed into the trash can has a hat which appears and disappears between shots.
In the opening credits, actress Sheila Frazier's name is correctly spelled "Sheila"; in the closing credits her name is misspelled "Shiela".
The man who takes a swing at Youngblood at the end of the movie is supposed to be the deputy commissioner, but it is clearly a double.
When Reardon has his detectives bring Priest to him on the docks, he tells him he will not let him quit. Priest calls him an obscenity and one of the detectives hits Priest. But whereas Reardon had been right in Priest's face, when the detective hits Priest, Reardon is suddenly gone. Obviously as the fight sequence was filmed, this actor was removed for his own safety, but the editing was very disjointed with his disappearance.
Priest's rationale for why he is NOT an evil drug dealer is the fact that he sells cocaine, not heroin, and after all cocaine is not addictive -- a common belief at the time. Subsequent events have proved how ridiculous his justification actually was.
When Scatter tells Priest the name of the "Man" who is supplying the drug trade, his mouth says "Red" but the audio says "Reardon." In addition, the audio is a totally different voice from the actor playing Scatter and was clearly added in after the film was shot.
The camera crew is reflected in panels of Priest's car during the opening shots.
When Priest orders Fat Freddy to get his money back, you can see the crew man behind the door as they leave the apartment.
During the opening foot chase, the camera cord becomes visible several times at the bottom of the screen.
