10. Lena Dunham
She's only directed, written and starred in one film. But 2010's Tiny Furniture is a hell of a calling card. It's a low-budget ($25,000) comedy of touching gravity that finds god in the details of family life – and the devil, too. Dunham's talent flourishes now on HBO's Girls, revolving around four frank-talking Manhattan friends, Hannah (Dunham), Marnie (Allison Williams), Jessa (Jemima Kirke) and Shoshanna (Zosia Mamet). It's Sex and the City done raw with no sentimental apologies. Dunham won Emmy nominations for acting and directing. She's only 26, so expect more awards in her future. It'll be fun to watch her move up and up on this list.
