Downton Abbey star Jim Carter is fronting a Greenpeace campaign ahead of the Christmas holidays by playing a dishevelled Santa Claus struggling to cope with climate change and oil drilling.

The Brit, who plays butler Carson on the hit Tv show, has swapped his bow tie and tails for a Santa outfit in a new promo for the environmentalist organisation.

In the film, titled An Urgent Message From Santa, Carter's Claus attempts to deal with the North Pole melting and flooding, as well as power failures.

The actor hopes the stark message in the short film will encourage viewers to go green this holiday season.

He says, "I want to do my part to help raise the profile of the threats posed to the Arctic by oil drilling and climate change. I was pleased to have this opportunity to support Greenpeace and their Christmas campaign.”
