Matt Smith turns 30 this Sunday! Here he is receiving a TARDIS-shaped birthday cake at MCM London Expo. Happy Birthday, Matt!
Leonard Nimoy turns 81 years old today. He introduced us to Spock, directed one of the best "Star Trek" films, and sang us the story of "The Hobbit." He's done so much, it's almost impossible to list every accomplishment here. He's even still going strong in the sci-fi world with a recurring role in "Fringe." Thanks for all you've given us sci-fi fans, Leonard. Happy Birthday!
