David Tennant to star in 'Extras'

David Tennant has lined up to appear alongside Ricky Gervais in a special edition of Extras, according to reports.

An 80 minute Christmas special will feature the Doctor Who star playing himself and making reference to his portrayal of the iconic Time Lord. An insider from the show is quoted by What's On TV as stating: "David's a huge fan of the show and extremely popular, so we've signed him up. He'll be in good company as we're lining up some other great names."

In a previous episode of Extras, actor Patrick Stewart poked light fun at his starring role as Captain Jean Luc Picard in Star Trek: The Next Generation.
