For nearly 20 years Claire Danes has maintained a career with excessive amounts of crying and "OMG I can't handle this!" facial expressions. It's sort of her shtick. Saturday Night Live took full advantage of this with their parody of Homeland with Anne Hathaway going total facial freak out. Even if you've never seen the Homeland, the sketch is a pretty hilarious gem of physical comedy.
That career of crying that I was talking about, see a tear filled retrospective with this lip quivering supercut.
