RUBY JERINS, 11
Doesn't ruin: Shutter Island (2010), Nurse Jackie (2009-present)
Why they don't suck: On Nurse Jackie, Jerins plays the protagonist's daughter, Grace Peyton, who, while unaware that her mom is a pill addict who cheats with a pharmacist to get fixes, has immense anxiety about the state of her family. Thanks to some brilliant acting on her part, we hear her cries for help loud and clear.
Child version of: Anne Hathaway
