According to The Hollywood Reporter, Kyle Killen's script has attracted the attention of Carrey, who would portray a man who walks around with a beaver puppet on his hand believing it to be real. Steve Carell was previously attached to the project.

Yes Man star Carrey can next be seen in Robert Zemeckis's A Christmas Carol, released in IMAX 3-D and conventional cinemas on November 6.
