Some actors worry about keeping strict control over how the world perceives them and making sure that they don’t get typecast, but Mad Men’s Christina Hendricks seems to think that if you look that good dressed up in the garb of the period, why not follow up your head turning, 60s-set breakout performance with another role steeped in the same decade? To that end, she has accepted a role in director Sally Potter’s upcoming anti-nuke movie Bomb, which tells the tale of a couple of teenage girls who become part of the Ban the Bomb movement and also learn a little bit about free love and their own blossoming sexuality along the way.There isn’t yet any word on what role Hendricks will play in the film, but she joins a cast that already includes Elle Fanning and Alice Englert as the main girls, and is also rumored to soon pick up names like Alessandro Nivola and Annette Bening as well.
