Trivia: RoboCop 2 had the 2nd highest body count for a film in 1990, with 58 deaths. It was beaten only by Die Hard 2, with 162 deaths. (They cheated by having an aeroplane blow up, of course).
Trivia: At the start of the film when the gang break into the weapons store we see two of them argue about the cops coming to get them. If you look closely at the gun rack on the far left of the screen you will see a Beretta M93R-AG gun. This is the slightly unmodified version of the Auto-9 gun that RoboCop uses.
Trivia: The abandoned hospital used in RoboCop 2 for Cain's death and brain removal scenes was the former Jefferson Davis Hospital in Houston, Texas. The building was demolished in 1999, and the property where the hospital was once located was sold off to the U.S Federal Reserve for $23 million.
Trivia: When Robocop's being reprogrammed, various information flashes up on screen, only really readable if watched frame by frame on a DVD. Various new directives come up, including 'Avoid Orion meetings' (Orion being the company that made the film). The names Kuran and Lockwood are shown among the garbage, being Peter Kuran and George Lockwood, two of the special effects team. There's also a string of numbers, which when treated as Hex and translated to ASCII comes out as 'Pete Kuran is a great guy'. (00:46:05)
Trivia: While producers loved Frank Miller's original version of the script, they quickly realized it was unfilmable as written. The final screen version was heavily rewritten and bears only a superficial resemblance to Miller's story. In 2003, Miller's screenplay was adapted into a comic book series titled, appropriately, "Frank Miller's RoboCop".
Trivia: When the police cruisers zoom past the hot dog stand and one guy remarks that they're not holding signs, that actor is Chad Lowe, younger brother of Rob.
Trivia: Nancy Allen reportedly hated the production. She signed on under a different director and script, and was very excited about the project, feeling it could be just as good as the original. When Irvin Kirshner replaced the original director, she felt he stripped out too much of the satirical humor of the original film, and they began to have creative differences. As a result, many of her important scenes were stripped down or removed altogether so they wouldn't have to deal with one-another. The situation was so bad, she only agreed to be in the third movie on the condition that she be killed off in the first act.
