Eddie Redmayne lends voice to new Thomas the Tank Engine film

The No. 1 blue engine is getting a new friend in Eddie Redmayne.

Fresh off an Oscar win for his portrayal of Stephen Hawking in The Theory of Everything, the British actor will be heard in the next instalment in the Thomas & Friends series, Sodor's Legend of the Lost Treasure. The 60-minute CGI feature will be released on DVD by HIT Entertainment in the fall of 2015.

Redmayne voices the role of Ryan, a new engine on the Island of Sodor whom Thomas meets on a quest.

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

Also joining in on the adventure are Harry Potter alums John Hurt, as Sailor John, and Jamie Campbell Bower as Skiff.

"It is a great show to be involved in and incredibly fun to record. I've thoroughly enjoyed my first animation and I look forward to everyone seeing the end result," said Bower.

"Sailor John was something of a departure from what I usually do and a lot of fun to play," added Hurt. "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."

This year marks the 70th anniversary of the Thomas the Tank Engine brand.
