The 41-year-old singer will play a Christmas elf in the film but he is still not sure when he will begin working on the project, reported Sun online.
"I don't know if I am even really meant to say, but I might be one of Santa's helpers in a film for Christmas. I think I am going to be one of the people who clean out the reindeers," he said.
Owen landed the role after agreeing to write a song for the film's soundtrack in return for a part.
