When we were at Comic-Con 2012 in San Diego, we got to see a screening of the upcoming action flick 'Dredd.' While we didn't get a close look at our guy Karl Urban, (duh, 'cause he kept his helmet on for the entire film) we did get a close-up snapshot of Lena Headey as Madeline “Ma-Ma” Madrigal. Let's just say, we were a little more than frightened.

If her role on 'Game of Thrones' is any indication, Headey is an intense actress. Cersei Lannister is one of those women who you do not want to cross, but Ma-Ma is way more terrifying; mainly because she looks and acts just as crazy as Heath Ledger's infamous Joker character from 'The Dark Knight.'

She's got that same wild look in her eyes, like she's going to make a pencil disappear; she took control of a ton of criminals in her pursuit for power (definitely Joker-esque); and she's already been called "one of the best screen villains of the year" ... by us.
