Derren Brown blew James Corden's mind, while Eddie Redmayne got Jimmy Fallon to... lick a card. 

Redmayne fully embraced his Harry Potter character Newt Scaramander and performed a magic trick for the host. Pulling out all of the stops, even gifting Fallon with a Hogwarts-style envelope, the Oscar winner did a trick that wasn't too shabby.
