"The Soup" host Joel McHale, Scott Bakula and various other comedic actors are joining Steven Soderbergh's darkly comic thriller "The Informant" for Warner Independent Pictures, Participant Media and Groundswell Productions says The Hollywood Reporter.

The film is based on Kurt Eichenwald's 2000 best-seller. Bakula and McHale, who is in final negotiations, will play FBI agents working with agri-business insider Mark Whitacre (Matt Damon) to stop a price-fixing scam.

Mike O'Malley (CBS' "Yes, Dear"), Andrew Daly ("Semi-Pro"), Adam Paul (Starz's "Hollywood Residential") and Melanie Lynskey (CBS' "Two and a Half Men"), Tom Wilson, Rick Overton and Tom Papa have also joined.

Despite the serious subject matter, Soderbergh is said to be looking at creating a thriller with dark comedy elements which is why he chose comedic actors who haven't been overexposed on film.

Principal photography is set to begin this month.
