Meet the next wave of Apatow all-stars.

Bo Burnham
After his hilarious YouTube videos made him a mini-Web-sensation, the 18-year-old was tapped for a role in Funny People by Apatow, who also commissioned Burnham to write a musical set in high school.

David Krumholtz
The star of CBS’s Numb3rs, Krumholtz had small roles in Freaks and Geeks (as Samm Levine’s older bro), Undeclared, Walk Hard, and Superbad. Next he’s starring in and writing Apatow’s upcoming Attorneys at Raw.

Ken Jeong
This real-life M.D. turned a taste for stand-up into roles in Pineapple Express, Funny People, and The Hangover. His outtakes on the Knocked Up DVD may be the funniest thing Apatow’s captured on-camera.

Samm Levine
Among the geekiest of Apatow’s Freaks and Geeks, Levine has parlayed stints on dozens of TV shows, including Ed and Veronica Mars, into a role as one of Quentin Tarantino’s Inglourious Basterds.
