Hollywood actors Ben Stiller and Samuel L. Jackson have agreed to appear in Ricky Gervais's latest sitcom, Extras.

The comedian's new show follows a group of extras on a film set, who spend their time hoping for one big line. Stiller (Meet the Parents) and Jackson (Pulp Fiction) will appear in one episode each.

Gervais told The Sun, "I am delighted. Ben is the finest comedy actor of the moment, while Samuel is a legend. They will both play extreme and twisted versions of themselves.

"The success of The Office in America means it is much easier for me to approach such big stars. Ben is a huge fan of The Office. He wanted to produce the US version but unfortunately didn’t have time. I had lunch with him and he said he’d love us to work together."

Other stars appearing on the series include Jude Law and Kate Winslet.
