Deliberate mistake: When the board member is shot up in the beginning by ED-209, in one or two shots you can see the bullet impacts happen about 1/2 a second after the shot starts (Criterion DVD version). (00:11:55)
Robocop (1987)
1 deliberate mistake - 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.
Answer: Most of his head and brain, about 40% of his upper torso, none of his pelvic area or limbs.
Answer: When Bob Morton is told by a tech that one of Murphy's arm was saved, Bob stated that he wants total body prosthesis. Meaning Robocop's entire body was synthetic. None of his actual body was used. The only thing that was used was Murphy's actual face.
Also, his human brain, and possibly his spine, where OCP could wire him into the suit.
