Robert Zemeckis has heaped praise on his A Christmas Carol co-star Jim Carrey.
The actor provides the central voice of Scrooge in the festive 3D movie that's set to hit cinema screens this week.
In an interview with Digital Spy the director said: "I've always been a fan of Jim and I know that he's a wonderful actor, a great dramatic actor, a great character actor and very physical actor.
"When he performs and uses every single muscle in his body to perform. I thought, 'That's what we need for motion capture cinema'."
"When you have an actor who's as versatile as Jim you've got to put him to work.
"You've got to use him anyway you can."
A Christmas Carol is an animated retelling of Charles Dickens classic novel about a Victorian-era miser taken on a journey of self-redemption, courtesy of several mysterious Christmas apparitions.
A Christmas Carol is out now.
