Video of the day: Relive Benedict Cumberbatch and Jimmy Fallon's tribute to Alan Rickman

They say imitation is the highest form of flattery, and nothing is more true when it comes to Benedict Cumberbatch and Jimmy Fallon's battle to see who can perform the best impersonation of the late actor Alan Rickman, who passed away on Jan. 14. Both stars held the Harry Potter actor in the highest regard, and Alan himself found humour in their ability to perfect his distinct accent. In June 2015, the star appeared on the late show the night after Benedict and Jimmy's "Rickman Off" and insisted the host apologize with the aid of a helium balloon. Watch both hilarious exchanges below!
