Jason Segel Movies and TV Shows: Complete Career Guide

If you’ve ever laughed at a deeply sincere, tall guy stumbling through a breakup or playing a lovable lawyer, you’ve met Jason Segel. Born in Los Angeles in 1980, Segel first caught attention on the cult classic Freaks and Geeks before becoming a household name as Marshall Eriksen on How I Met Your Mother. This guide maps his filmography, explores his creative risks as a writer-producer, and separates verified facts from lingering questions about his career and personal life.

Film debut: 1999 ·
Breakout role: How I Met Your Mother (2005–2014) ·

Creative frustration in later seasons
