Sam Trammell of “True Blood” has joined the cast of indie drama “Long Time Gone” alongside Virginia Madsen and Anthony LaPaglia.

Smokewood Entertainment is producing the film, with co-founder and producer Sarah Siegel-Magness (“Precious”) making her directorial debut.

Production began Sept. 12 in Los Angeles. Trammell began work Monday.

“Long Time Gone” also stars Zach Gilford, Amanda Crew and newcomer Graham Rogers. Karen McCullah (“The Ugly Truth”) wrote the screenplay based upon April Stevens’ novel “Angel, Angel.”

Story follows a broken family who must cope when the husband (played by LaPaglia) leaves his wife (Madsen) for another woman. Their sons have no idea what to do when their mother refuses to come out of her bedroom for days and then weeks.

Trammell plays an easy-going landscaper who hires one of the sons as a day laborer and befriends his distraught mother.

Bobbi Sue Luther, Gary Magness (“Precious”) and screenwriter McCullah are producing. Andrew Sugerman and Seth Jaret are exec producing.

Shooting will continue until Oct. 25.
