Watch: Michael Sheen and Nathalie Emmanuel reveal favourite Christmas movies

Michael Sheen and Nathalie Emmanuel will be hoping their new movie Last Train to Christmas becomes a festive favourite but, in the meantime, they've revealed the Christmas films they watch every year.

The Game of Thrones star added: "I also like The Grinch. I watch that a lot as well."

For Sheen, his go-to choice for festive entertainment is a more traditional and long-lasting pick from the 1940s.

"The classic for me is It's a Wonderful Life. It always never fails to move me and inspire me. I love it," Sheen said, adding that there might be a new pretender to the crown.

"But I have to say, coming up on the rails the last few years, Elf is threatening to take over. It has become a favourite."

In Last Train to Christmas, Sheen plays nightclub promoter Tony Towers, who discovers he can travel through his own past and future by moving through the carriages of his train home for a festive gathering.

He discovers his actions in other carriages have knock-on effects, changing his present day and his relationship with his girlfriend — played by Emmanuel.

The cast of the film, written and directed by Julian Kemp, also includes Cary Elwes as the wayward brother of Sheen's character.

Last Train to Christmas is a key part of Sky and NOW's festive schedule, which also includes several other new Christmas films in A Christmas Number One and the gaming-inspired 8-Bit Christmas.
