Robocop 2- An attempt to replace Robocop with a new Robocop goes wrong,
mainly because the brain used in the second robocop belongs to a psychopath who
introduced a highly addictive new drug to Detroit. Frank has a cameo as a drug
chemist named Frank.

Robocop 3- Robot ninjas and Robocop can fly. Now I love Franks work, and I
don't know how much of this story is actually his, but this movie, well, is less than
great.
