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.
Robocop (1987)
1 plot hole - chronological order
Directed by: Paul Verhoeven
Starring: Ray Wise, Ronny Cox, Peter Weller, Miguel Ferrer, Nancy Allen, Dan O'Herlihy, Kurtwood Smith
Continuity mistake: Dick Jones brags (admits?) to Robocop, "I had to kill Bob Morton because he made a mistake. Now, it's time to erase that mistake" while Robocop is crouched on the ground, not only looking away from him from across the room, but also Robocop's eyes are in a vertical position. In the playback, Jones is facing the camera as though it were videotaped or filmed in a studio. (01:10:50 - 01:35:10)
[After ED-209 kills a junior executive.]
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.
