He’s Geeky Because: His geek cred via Sherlock is obvious, but Cumberbatch will also provide the voice of Smaug/The Necromancer in The Desolation of Smaug. That’s mega-huge! Oh, and he also played one of geekdom’s most famed men, Stephen Hawking, in a 2004 TV movie. Our favorite Sherlock is also a total theater geek, and has been known to delve into painting in his spare time. Thus, his Geek-O-Meter Rating is kinda off the scales right now.
