Despite "The Hobbit: Battle of Five Armies" cast Benedict Cumberbatch's busy schedule, he still found time to take part in the star-studded Monaco Grand Prix last Sunday. The "Sherlock" actor was spotted looking dapper as ever in his navy blue suit and white-collared shirt. 

He was there on behalf of Sky Sports to do post-race interviews where he was able to talk with Lewis Hamilton. 

When Benedict Cumberbatch asked Lewis about the race won by Nico Rosberg, the Brit driver answered: "Unfortunately he didn't make any mistakes."
