Billy Crystal has joined animated movie project Which Witch as a writer, producer and star.
The Jim Henson Co is behind the adaptation of Eva Ibbotson's 1979 book in which a wizard holds a contest among the seven witches of Todcaster to determine which witch he will marry.
Monsters Inc star Billy - who voiced one-eyed Mike in the Disney-Pixar franchise, has now signed up to the movie in a big way, reported Variety.
Billy said: "When Brian Henson called me about it, I didn't know the book. But it's a fantastic story, and I brought in a wonderful writer, Michael Feldman, and we've written a terrific and inventive script. I'll play a character as well, which will be great fun because he actually has two eyes."
Production is expected to begin next year with the late Jim Henson's son Brian directing and producing.
