Moe, Larry and Curly are almost complete. MGM and the Farrelly brothers are negotiating with Jim Carrey and Benicio Del Toro to join Sean Penn for the slapstick trio.

The studio has already set Penn to play Larry. They are also zeroing in on Carrey to play Curly and Del Toro to play Moe to complete the set.

Variety also reports that Carrey is already making plans to gain 40 pounds to be at par with Curly's rotund physique.

The slapstick comedy will center around the antics of the trio - Moe Howard, Larry Fine and Curly Howard - in the Columbia Pictures shorts during the 1930s and '40s. Comedy team, Peter and Bobby Farrelly ("My, Myself and Irene," "Shallow Hal," and "There's Something About Mary"), wrote the script and are producing with their Conundrum partner Bradley Thomas and Charlie Wessler.

Production is set to kick off in the early fall for a 2010 release date.
