When I first came to the States, I thought I had a perfect American accent, and then I was abruptly becoming aware that it wasn't. So I did have to work on it a little bit, but I was hesitant working on it because I thought it was good.
The original 'RoboCop' was X-rated, and then they had to cut it down so it became R-rated, and Verhoeven claimed that actually made the movie more violent, because it's what you don't see that actually scares you.
