John Francis Daley is an American filmmaker and actor. He is best known for playing high school freshman Sam Weir on the NBC comedy-drama Freaks and Geeks and FBI criminal profiler Dr. Lance Sweets on the crime drama series Bones, for which he was nominated for a 2014 PRISM Award. He plays keyboards and sings for the band Dayplayer.

Freaks and Geeks is an American teen comedy-drama television series created by Paul Feig and executive-produced by Judd Apatow that aired on NBC during the 1999–2000 television season. The show is set in a suburban high school near Detroit during 1980–81. The theme of Freaks and Geeks reflects "the sad, hilarious unfairness of teen life". With little success when it first aired, due to an erratic episode schedule and conflicts between the creators and NBC, the series was canceled after airing 12 out of the 18 episodes. The series became a cult classic, and Apatow continued the show's legacy by incorporating the actors in future productions.
