20th Century Fox has signed on the Jonas Brothers for their feature starring debut in Walter the Farting Dog, based on a bestselling series of books by William Kotzwinkle and Glenn Murray.

According to Variety, the film is being adapted by Alec Sokolow and Joel Cohen into a family film that will revolve around Nick, Joe and Kevin Jonas, as well as their younger brother Frankie.

The title character in the "Walter" books is a fat dog with severe flatulence. The brothers play musicians whose parents are asked to care for the dog by an aunt just before she passes away.

The film will shoot next spring and is a potential directing project for Peter and Bobby Farrelly, who'll produce with Bradley Thomas through the trio's Conundrum banner.
