3. EMMA STONE

Movie: Superbad (2007)
It’s the movie that introduced audiences to one of the greatest up-and-coming actresses of this generation. Stone plays Jules, the host of a party that the boys Seth (Jonah Hill) and Evan (Michael Cera) are trying to get alcohol for. The fact that her character was totally cool with being accidentally headbutted by a drunk Seth lets us know how ride-or-die she is.
