Olivia Colman and David Walliams to star in Pudsey The Movie

Olivia Colman and David Walliams are to star in Pudsey the Dog: The Movie, a family adventure featuring the nation's favourite pooch, Pudsey the dog, who won Britain's Got Talent in 2012.

Little Britain star David will be the voice of the cute canine, while Broadchurch's Olivia will be the voice of a horse called Nelly.

The shaggy dog tale sees Pudsey as a down and out stray in London, whose life is transformed when he makes friends with a family. Mum Gail, played by Harry Potter star Jessica Hynes, is recently widowed and she and her three children Molly, George and Tommy move to the countryside village of Chuffington, so Pudsey decides to tag along.

But as the family and their new pet settle in to their new home, evil landlord Mr Thorne and his devious cat Faustus have a sinister plan up their sleeves, and it's down to Pudsey to save his new adopted family and the whole village.

Watch out, too for ex-Emmerdale star, Luke Tittensor who also pops up in the adventure as Will, a resident of Chuffington who befriends the family.

Pudsey the Dog: The Movie will open in cinemas on July 18 this year.
