Gabriel Mann, Eliza Dushku and John Savage are set to join the indie film "The Thacker Case" reports Reuters.

The story centers on around the mysterious death in 1983 of repeat drunk driving offender Kevin Thacker and the discovery of his body in an alley behind the Marshalltown, Iowa, police department after his latest DUI arrest.

Mann will play Pepper, a young up-and-coming attorney who launches his career by landing the controversial case, which required him to wade through law enforcement corruption and cover-ups. Ultimately, Pepper gained national attention from the case.

Dushku will play Monica Wright, a young attorney and Pepper's loyal assistant. Savage will play Thomas Thacker, Kevin's father, who enlists the help of Pepper to discover the truth behind his son's death.

Robert Dean Klein wrote the screenplay based on the story written by attorney Stuart Pepper. Brian Jun is directing. Shooting began this week in Los Angeles and Iowa.
