Continuity mistake: When Robin Williams is being questioned by the police for the first time, one of the cops is talking to him. Very soon afterward the cop leaves the room and is walking away. We see the cop in the distance in another room, yet we hear the cop talking to Robin Williams again as Al Pacino shuts the door. Almost immediately, the camera angle changes to the cop as he finishes talking. He is standing in front of Robin Williams again.
Continuity mistake: When Al Pacino runs along the boardwalk towards the floating logs, following Robin Williams, in the shots showing him from behind he is running with his arms spread at a considerable angle, while in the shots showing him from the front, he is keeping his arms into his body. (00:25:20)
Continuity mistake: During the final fight, Pacino & Williams shoot it out in a small boathouse. Williams is shot and rolls into the water (dropping about 2 foot before splashing in). Pacino walks out of the house and meets the female officer. The camera pulls back to show the boat house on stilts about 20 feet out of the water.
