Scarlett Johansson certainly likes to diversify when it comes to her work projects, and this year we should get to experience the full breadth of what she can do. She'll appear as a stereotypical early-20s New Jersey woman alongside Joseph Gordon-Levitt in Don Jon, turning on her best possible Jersey Shore-esque accent for the role. She also was, once again, ranked highly on the Maxim Hot 100 list, coming in this year at No. 15. While she doesn't have any stage or musical project in the works like she has in the past, she has become quite politically active as she supports Scott Stringer's run for mayor of New York City.
