Turns out Eddie Redmayne doesn't 'Know It All' but it was nice of Lily Collins to let him win the Harry Potter round.

J.K. Rowling and Warner Bros. don't have to be embarrassed of him now at least.

Eddie Redmayne and Lily Collins faced off in Jimmy Fallon's game of knowledge and deception, 'Know It All', to see who could name more Harry Potter characters, body parts and pop singers and while they were both too politely British to attempt a lie, Collins really played the game and made a holy show of Redmayne.
