Kevin Rankin has landed another big-time guest-starring role.
The former Friday Night Lights actor - who has appeared on Lost, Grey's Anatomy and will show up on the September 30 episode of The Mentalist - will play the son of a "hard line of polygamists" on Big Love, according to The Hollywood Reporter.
No return date has been set for Big Love, but the show is expected to premiere on HBO in January.
