Watch Charlize Theron Become Enraged in Young Adult Red Band Spot

Charlize Theron said recently that she took a four-year break from acting to work with her production company, so it's interesting to consider what about Young Adult (besides the Oscar-friendly duo of Jason Reitman and Diablo Cody) would drag her back into the craft. Here's an idea: She gets to be profane, uncompromising, and really, really pissed off. In this red-band spot for the new film (out December 9), Theron loses her shit with Elizabeth Reaser, who plays her ex-beau's (Patrick Wilson) new wife. Yikes.

She's quite not Mommie Dearest livid, but Theron's character Mavis is a snide, warped version of Faye Dunaway's famous nutjob here -- not to mention entitled, condescending, and superficial. Young Adult could really be called "The Modern Asshole Lady." Tthankfully it's not, so that title can now go to the awesome new Conde Nast publication I'm planning.
