John Francis Daley began acting as Tommy in the national and international tour of the Broadway smash hit, The Who's Tommy. He came to national attention when he was cast in the lead role of "Sam Weir" in the critically acclaimed Judd Apatow-produced television series Freaks and Geeks alongside Seth Rogen, James Franco and Jason Segel.

In 2007, Daley and his writing partner, Jonathan Goldstein, sold their first screenplay, The $40,000 Man, and have since sold several other films to major studios. The pair was hired to pen the reboot of Vacation, the 1983 classic starring Chevy Chase. They also wrote the film Horrible Bosses. A box office success in summer 2011, Horrible Bosses starred Jennifer Aniston, Kevin Spacey, Jamie Foxx, Jason Bateman and Colin Farrell. In addition to writing the script, Daley plays a cameo role in the film.
