Ethan Hawke Is 'Jealous' of 'Boyhood' Star's Good Looks (Video)
Ethan Hawke says he watched his onscreen son Ellar Coltrane grow from a small boy into a "total stud" who looks like "James Dean" — and he's not always happy about it.

Earlier on NBC, Jimmy Fallon lightened the mood by throwing balls at Julia Roberts' face. (Don't worry, she got to do the same to Fallon.)
