A decade after the first RoboCop movie was produced, Neumeier rejoined Paul Verhoeven to work on Starship Troopers, which was adapted from the novel with the same name by Robert A. Heinlein in 1959. With violence and satire thrown into a story of efforts by the human race to ensure its survival (in ways similar to RoboCop at times), Starship Troopers was more successful in Europe, Asia, etc., than in North America where it drew gross ticket sales of about $54 million at theaters, although Artforum magazine selected this film as one of the "10 most artistic [film] achievements of 1997". Neumeier also appeared in this film in the brief role of a man convicted of murder and sentenced to immediate execution.
Neumeier also co-produced RoboCop, which was released in movie theaters in 1987 in North America and some other locations. This movie was a success, and it drew just over 50 million dollars' worth of ticket sales in the United States alone. The success of RoboCop also motivated the production of two sequels, RoboCop 2 and RoboCop 3, and also two TV series, one live-action and one animated. Most of the creators of RoboCop had left before the production of these sequels.
The first sequel to RoboCop, RoboCop 2, was planned to have its screenplay written by Neumeier and Miner. He and Miner had written a dated rough first draft of a screenplay for RoboCop 2 in 1988 called The Corporate Wars. However, due to the 1988 Writers Guild of America strike, Neumeier was unable to write any more of the screenplay. The Orion Pictures company next decided to hire the comic book Artist Frank Miller to work on his own screenplay for RoboCop 2.
In January 2018, it was announced that Neumeier was writing a direct sequel to the 1987 film that would ignore the two previous sequels and the 2014 remake. “We’re not supposed to say too much. There’s been a bunch of other RoboCop movies and there was recently a remake and I would say this would be kind of going back to the old RoboCop we all love and starting there and going forward. So it’s a continuation really of the first movie. In my mind. So it’s a little bit more of the old school thing” Neumeier said.
