Choke has just added another member to it's already impressive cast list. According to Variety, Dexter's Brad William Henke will be joining Sam Rockwell and Angelica Huston in the film adaptation of Chuck Palahniuk's novel.

The book focuses on Victor Mancini, to be played by Rockwell, a medical-school dropout who has devised an ingenious scam to pay elder care for his Alzheimer's-afflicted mother. He pretends to choke on pieces of food while dining in upscale restaurants. He then allows himself to be "saved" by fellow patrons who, feeling responsible for Victor's life, go on to send checks to support him. When he's not pulling this stunt, Victor cruises sexual addiction recovery workshops for action, visits his addled mom, to be played by Huston, and spends his days working at a colonial theme park.

Henke will play the best friend of Rockwell's Victor Mancini. Actor Clark Gregg, best known for his stint on the sitcom The New Adventures of Old Christine, is directing the film.

Choke is currently shooting in New Jersey. It will be released sometime in 2008.
