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 ''Series/HowIMetYourMother'' and as the lead in ''Film/ForgettingSarahMarshall'', which [[WrittenByCastMember he also wrote]]. He is also known for working with director/producer Creator/JuddApatow, most notably in the [[ScrewedByTheNetwork short-lived TV shows]] ''Series/FreaksAndGeeks'' and ''Series/{{Undeclared}}'', and the movies ''Film/KnockedUp'' and ''Forgetting Sarah Marshall''.

He starred in and wrote the 2011 film ''Film/TheMuppets''. 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 ''Film/GetHimToTheGreek''.

----
* ActorSharedBackground: He's half-Jewish like his character Tom in ''Film/TheFiveYearEngagement''. A marginal case for ''Series/HowIMetYourMother'', 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.
* AuthorAppeal: As he's also a musician and songwriter, some of his songs will find their way into his projects.
* DyeingForYourArt: Lost 30 pounds for ''Film/TheFiveYearEngagement''. Averted with Marshall's famous head-shave in the Season 2 finale, as he refused to do it for real.
* ProductionPosse: Collaborates with Judd Apatow a lot.
* StarMakingRole: ''Series/FreaksAndGeeks'' gave him a cult fanbase, but ''Series/HowIMetYourMother'' gave him national attention.
* WrittenByCastMember: He wrote ''Film/ForgettingSarahMarshall'' and co-wrote ''Film/TheMuppets'' and ''Film/SexTape''.
