53. Aubrey Plaza
Biggest accomplishment this year: Starring in this August's The To Do List, her first movie as a leading lady
It is genuinely really difficult to tell how much of Aubrey Plaza's dry, deeply sarcastic sense of humor is an act and how much is genuine, and she probably prefers it that way. The Parks and Recreation star has seen her profile rise this year and will appear in upcoming movies The To Do List and Monsters University. She also made headlines for her thoroughly bizarre stage crash of Will Ferrell's acceptance speech at the MTV Movie Awards, which at first seemed staged but apparently wasn't, since Plaza was promptly thrown out of the event. It hasn't seemed to do much damage to her career, though, as she's since filmed a role in A Many Splintered Thing and will surely have several more projects coming her way.
