John Cameron Mitchell has settled on the perfect follow-up to Hedwig and the Angry Inch, his acclaimed directorial debut in which he stars as an East German transsexual rock singer. "I'm writing a children's film now," the 38-year-old actor-filmmaker tells TV Guide Online. "It's my version of a Willy Wonka-type story."

Titled Grandmaphone, the project — which Mitchell says will be live action with some computer animation — centers on the relationship between a little boy and his grandmother. Although the theater-trained performer hasn't even started casting the pic, he originally envisioned the late Madeline Kahn playing the grandma role.

Given all of the accolades being heaped on Mitchell for his work in front of and behind the camera on Hedwig, he shouldn't have too much trouble drumming up financing for Grandmaphone. On Monday, fellow openly gay thesp Sir Ian McKellen presented Mitchell with the National Board of Review's award for outstanding directorial debut. And on Jan. 20, he'll be attending the Golden Globes, where he'll face off against Gene Hackman, Hugh Jackman, Ewan McGregor and Billy Bob Thornton for best actor in a musical or comedy.

How does Mitchell size up his Golden odds? "I'm not going to win," he insists. "I mean [I'm up against] Gene Hackman. I'm just going to have a good time. It's the Golden Globes — it's going to be a hoot!"
