Plot hole: When Murphy is in the changeroom at the station, he learns that an officer has just died and that his funeral (according to the captain) would be the next day. There's simply no way a funeral can take place one day after someone's death. All the planning, prep work and getting the body released to the funeral home would take about a week...plus many other things. Simply cannot be done.

Visible crew/equipment: When Clarence Boddicker (Kurtwood Smith) is killed by Murphy (Peter Weller), Boddicker falls into the steel mill's water, blood spewing from his neck. Sharp eyes are required here to see that there is someone standing against the wall in the background... (01:32:40)

Dick Jones: I'm sure this is just a glitch. A temporary setback.
The Old Man: You call this a GLITCH?
Trivia: ED-209's voice is provided by producer Jon Davison. He was recorded as a placeholder, but the filmmakers kept it for the theatrical release. ED-209's roar is a jaguar growl played backwards.
