Jay Mohr is the latest actor to join the cast of Steve Carrell's new comedy Burt Wonderstone.
The US Office star is producing the movie in which he plays a traditional Las Vegas magician who finds himself upstaged by a rival - and "hip street magician" - played by Jim Carrey, who is stealing his thunder.
Jerry Maguire star Jay will play a magician named Rick The Implausible, according to movie blog The Wrap.com.
The cast also includes Olivia Wilde, Steve Buscemi, and James Gandolfini.
The latest version of the script has been rewritten by Up In the Air's Jason Reitman and 30 Rock's Don Scardino is directing.
