LONDON -- Ricky Gervais, creator of the worldwide comedy hit "The Office" says his star-studded new TV show will focus on the misadventures of a dwarf actor.

Gervais, the insult-slinging host of the Golden Globes, has already tapped Steve Carell, Johnny Depp and Liam Neeson to make guest appearances on the mockumentary, called "Life's Too Short."

The show follows the daily life of a dwarf actor -- played by Warwick Davis -- who runs a talent agency for fellow dwarves but keeps the best parts for himself. Gervais described the show as a cross between "The Office," and his showbiz-themed comedy "Extras."

The seven-part show launches on the BBC this fall. Gervais has said if Davis isn't a success, "I'll eat Johnny Depp's hat."
