Chief Judge Headey?

If reports are to believed on the internet seems like Lena Headey is up for a part in the new Dredd movie , apparently for the part of the main villian Ma Ma , but I can't see that myself seeing as the character is meant to be a large lady so unless Lena's going on a Raging Bull style cake eating binge or they CGI her character like Eddie Murphy in the nutty professor I'd  hazard a guess that she'll be playing Dreddy's boss The Chief Judge , then again I might be wrong. For my other Lena Headey posts here's the links http://leatherbeauty.blogspot.com/2009/02/emma-peel-poll-winner.html
