Jason Jordan Segel (born January 18, 1980) is a very tall and very funny actor and writer. He is best known as Marshall Eriksen on How I Met Your Mother and as the lead in Forgetting Sarah Marshall, which he also wrote. He is also known for working with director/producer Judd Apatow, most notably in the short-lived TV shows Freaks and Geeks and Undeclared, and the movies Knocked Up and Forgetting Sarah Marshall.
He starred in and wrote the 2011 film The Muppets. Those who find this strange should remember the Dracula Puppet Musical from Forgetting Sarah Marshall, which he also wrote.
He also co-wrote the Infant Sorrow music for the movies Forgetting Sarah Marshall and Get Him to the Greek.
He makes anything he appears in much, much better, especially if he sings or plays music.

- Actor-Shared Background: He's half-Jewish like his character Tom in The Five-Year Engagement. A marginal case for How I Met Your Mother, where his character Marshall wants to be a lawyer - Jason's father had been a lawyer. Marshall is also a former basketball player, as Jason is in real life too.
- Author Appeal: As he's also a musician and songwriter, some of his songs will find their way into his projects.
- Dyeing for Your Art: Lost 30 pounds for The Five-Year Engagement. Averted with Marshall's famous head-shave in the Season 2 finale, as he refused to do it for real.
- Production Posse: Collaborates with Judd Apatow a lot.
- Star-Making Role: Freaks and Geeks gave him a cult fanbase, but How I Met Your Mother gave him national attention.
- Written by Cast Member: He wrote Forgetting Sarah Marshall and co-wrote The Muppets and Sex Tape.
