Carrey and Diaz....it's a no go

Jim Carrey and Cameron Diaz have pulled out of the romantic comedy A Little Game Without Consequence less than a month before filming was set to get underway.

A source told E! Online that Carrey and Diaz's change of heart was due to creative differences- specifically the actors were said to be unhappy with the latest version of the script written by the movie's Italian director, Gabriele Muccino.

Carrey's next movie, mystery thriller The Number 23, is due out next year. He is also lending his voice to a big-screen animated version of Dr. Seuss' Horton Hears a Who.

Diaz will be seen opposite Kate Winslet and Jude Law in the romantic comedy The Holiday, due out Dec. 8
