Eddie Redmayne is to star in a new Thomas the Tank Engine film, Digital Spy reports.

The Oscar-winning actor will lend his voice to Sodor's Legend of the Lost Treasure, which is being released to celebrate the 70th anniversary of Thomas & Friends.

Redmayne will voice new engine Ryan, while John Hurt and Jamie Campbell Bower will also record for the film.

"I grew up loving to watch Thomas and his pals getting caught up in unexpected and mischievous adventures," Redmayne said.

"I jumped at the opportunity to get involved and what fun it was! I have never voiced an animated character before, and I had a complete blast."

Hurt, who plays Sailor John, added: "I remember watching Thomas the Tank Engine with my children when they were young and I'm delighted that it continues to appeal to each successive generation.

"I enjoy working vocally and have voiced many animated characters. Sailor John was something of a departure from what I usually do and a lot of fun to play."

Sodor's Legend of the Lost Treasure will be released on DVD in 2015.

Redmayne recently won the Best Actor Oscar for his portrayal of Stephen Hawking in The Theory of Everything.
