An eagerly anticipated TV comedy series continues to attract high-profile stars, Reuters reports. Highly regarded actors Helena Bonham Carter and Liam Neeson have joined the cast of the new series from Ricky Gervais, “Life’s Too Short.”

The BBC sitcom focuses on an actor of short stature, played by Warwick Davis, who runs a talent agency. It is set to begin airing later this year in Britain on BBC Two and is due in the U.S. in 2012, on HBO.

The show is described as a fake documentary along the lines of two previous Gervais series, “The Office” and “Extras.” It is written and directed by Gervais and Stephen Merchant, a longtime Gervais collaborator.

Other well-known actors who are on tap to appear in the show include Johnny Depp and Steve Carell.
