Segel, Helms team for stoner comedy 'Jeff'

Jason Segel and Ed Helms will team up to star in stoner comedy Jeff Who Lives At Home.

The movie, written and to be directed by Mark and Jay Duplass, involves two brothers, one (Segel) who still lives at home with his mother and the other who has moved out and is married but overbearing.

Judy Greer is in talks to play Helms's wife, while the mother role is yet to be cast, according to The Hollywood Reporter.

Segel and Helms are both stars on US TV, in How I Met Your Mother and The Office respectively, but have been moving towards features recently. Segel topped the cast of Forgetting Sarah Marshall and Helms was part of The Hangover's ensemble.
