Cast Joins Gervais' Truth

Jonah Hill and comedian Louis C.K. will play Ricky Gervais' neighbors in the Warner Brothers fantastical movie This Side of the Truth, according to The Hollywood Reporter.
They join Jennifer Garner and Rob Lowe in the film, based in a world where lying doesn't exist. The story centers on Mark (Gervais), an average guy who discovers his newfound ability to tell untruths and uses the skill in his effort to seduce a woman (Garner) who is way out of his league. Hill (Superbad) will play Mark's humorous neighbor who also suffers from depression, while Louis C.K. will play Mark's loser best friend. Gervais makes his feature-film directing debut with the movie and is co-writing and co-directing with Matt Robinson. Production is set to begin in April.
