Gary Oldman has done a lot in his long and illustruous career. But he's never been a part of the Marvel Cinematic Universe. He's certainly open to the prospect though.
Whether you know of it previously through the Sylvester Stallone lead 1995 movie, the Karl Urban 2012 movie, or the original 2000 AD comic series, you'll certainly know of Judge Dredd. Soon though, the judges and the criminals they take down are headed to a TV screen near you.
