Comedians Tim Heidecker and Eric Wareheim have confirmed that Will Ferrell, John C. Reilly, Zach Galifianakis, Robert Loggia, and Jeff Goldblum will all appear in the pair’s currently shooting comedy, Tim and Eric’s Billion Dollar Movie. In the film, the duo, who are playing themselves, lose a billion dollars they have been given to make a movie, and take over a semi-abandoned mall in an attempt to recoup the cash. Ferrell portrays the mall’s former owner, while Reilly plays a character called Taquito. ”Taquito’s made the mall his home,” says Heidecker, who is co-directing the film with Wareheim. ”He’s a sick man-boy.” The stars of Adult Swim’s bizarre cult sketch series Tim and Eric Awesome Show, Great Job! deny a recent Internet rumor that Harrison Ford has been cast in the movie. ”Obviously that’s something Harrison Ford’s people planted,” jokes Heidecker. ”He’s been trying to work with us for years.”
