Visible crew/equipment: In the scene where Jack approaches Parry's bed, a crew member is seen on the right hand side of the shot wearing a walkie talkie. He inches out of frame in 3 or four seconds. (01:51:05)
Continuity mistake: At the beginning of the film, Jack is talking to soon to be murderer Edwin. He tells the caller that yuppies must be stopped, in a calm tone, later when Jack is watching the news in his penthouse, the call is played on the news and Jack's tone is hostile.
