Stephen Fry has signed up to appear in his first US sitcom, a project seen as Fry's attempt to emulate his ex-partner Hugh Laurie's success in Hollywood with House.

The actor, TV host, gadget-fancier and writer is to star in CBS pilot Super Clyde, which features "a meek, unassuming fast food worker who decides to become a superhero".

Meek, unassuming? That will not be Fry's role, the fast food worker is played by Rupert Grint who played Ron Weasley role in the Harry Potter movies.

Fry will play sidekick Randolph the butler – "the Alfred to Clyde's Bruce Wayne", says the Deadline website, which announced the news. The writer is Greg Garcia, whose previous credits include My Name Is Earl.
