David Walliams is joined by Hugh Bonneville for a Christmas special, with the Downton actor playing a grammar-obsessed vicar, a toothsome gameshow host and a yoga guru with anger issues. To his credit, he hurls himself into this sorry business with vim, but even with sketches featuring, in one case, the combined heft of Biggins, the Chuckle Brothers and Bob Carolgees, the material just isn't up to snuff.

Pushed back in the schedules due to a last-minute George Michael tribute at 10pm, this extended episode of Walliams And Friend, is a Christmas special, as well as being the last in the series, star of Downtown Abbey and W1A, Hugh Bonneville, partners with David Walliams for a variety of comedy sketches.

Hugh demonstrates his comic versatility as he plays roles as diverse as Alan Sugar, dishing out the hardest ever Apprentice tasks, and even the Countess of Grantham in her new commercial.

In addition, Hugh and David pair up to play smarmy game show hosts of the completely baffling "Double Or Nothing", the world's most embarrassing dancing dads (pictured) and even Bruce Wayne and his loyal butler Alfred.

Also features mini festive episodes of Middle Class Jeremy Kyle and Celebrity Slammer.
