I know it sounds crazy, but we all have seen AMDS digital tricks on youtube where the guy can create Robocop vs Terminator fights or Neo vs Robocop fights and put both character into the same frame.
I would suggest to the memory of all wounded Dredd fans, that AMDS, or anyone able to, would digitall put that helmet back on Stallone on all The Dredd movie (Stallone over at AICN agrees he should have kept that helmet on).
Anyone want to redo the movie that way ???
