Today he's best known for his role as Marshall Eriksen on "How I Met Your Mother." Before he hit the airwaves on CBS, however, Jason Segel was part of another show that's achieved a bit of a cult following. "Freaks and Geeks" was only on for one season, but it was a major factor in helping to launch Segel's Hollywood career.
Jason Segel was born Jan. 18, 1980 in Los Angeles, Calif., to parents Jillian and Alvin. He began performing at a place called Palisades Playhouse when he was in high school. From there, his entertainment career took off, and he appeared in his first film, "Can't Hardly Wait," in 1998. Segel has since appeared in many films and provided the voice for several animated characters, including Vector in "Despicable Me."
