Well, I guess if you are looking to cast an unlikely couple, then Ewan McGregor and Jim Carrey would probably be at the top of the list. Variety reports that McGregor has signed to play the romantic lead opposite Jim Carrey in the black comedy, I Love You Philip Morris. The film centers on Steven Russell (Carrey), a Texas conman who fell in love with his cellmate, Phillip Morris (played by McGregor). The script is based on the true story of Russell and his various escape attempts to be with his true love. Some of the more elaborate attempts included "using a green pen and bucket of water to change his prison outfit into what appeared to be surgical scrubs, another time by faking his death from AIDS and signing his own death certificate". But all did not end well for the lovers and while Morris eventually made it out of prison, Russell managed to earn a 144 year sentence for his various escape attempts.

The film is the directorial debut of Glenn Ficarra and John Requa, who are best known as the writers of Bad Santa. Ficarra and Requa also wrote the script based off of crime reporter Steve Mcvicker's novel. The film is set to start production as soon as Carrey is finished with Robert Zemeckis' latest foray into motion capture, A Christmas Carol (where Carrey is set to play multiple parts). McGregor has already lined up the Hitchcock-inspired Number 13 and the big-screen version of I, Lucifer for 2008. Plus, he has just finished work on The List with Hugh Jackman -- now that's the on-screen couple I've been hoping for; but no such luck.
