Santoro joins Jim and Ewan's Love-fest
He joins Knocked Up's Leslie Mann - who appeared with Carrey in 1995's The Cable Guy - in the cast for the film, which has been adapted from Steve McVicker's book by the team behind Bad Santa and Cats And Dogs, John Requa and Glenn Ficarra.
The movie is based on the true story of Carrey's character, con artist and married father-of-four Steven Russell, who falls for Phillip Morris (McGregor) when he is sent to prison in Texas.
Following his cellmate's release, Russell mounts repeated escape attempts to be reunited with the object of his affections.
The site reports that Carrey and McGregor recently visited a popular gay bar in Miami in preparation for their roles.
