Jason Segel says playing a lovable loser comes naturally

If there's one character actor Jason Segel seems to have mastered, it's that of the lovable loser. He began his career playing one on the television show "Freaks and Geeks" as a high school stoner with an unrequited crush. In "Forgetting Sarah Marshall," he played a dopey guy kicked to the curb by his more successful and attractive girlfriend. And in "I Love You, Man," his schlubby character spent his days playing guitar and picking up women at open houses. 

In "Jeff, Who Lives at Home," the latest project from sibling filmmaker team Mark and Jay Duplass, Segel tackles the archetype again. This time he's Jeff, an idealistic 30-year-old who lives in his mother's basement, takes bong hits and finds meaningful signs in late-night infomercials.
