To celebrate the release of Last Train To Christmas, the new Sky Original Film released this weekend, we sat down with its stars and get our Santa hats at the ready.

Tony Towers (Sheen) is about to take the trip of a lifetime. It’s 1985 and he’s a successful nightclub manager, a local celebrity and engaged to a much younger woman, Sue (Emmanuel). Things are going great. But when he embarks upon the 3:17 to Nottingham for a Christmas family reunion, things get a little strange. Moving up a carriage to the buffet car lands him in 1995, where he finds his clubs have failed and his life has fallen apart. Tony discovers that by moving up and down this fateful train, he can transport himself forward and backward to various stages of his life. Not only that, but the actions he takes in one carriage directly affect his life in the next. The question is, can Tony change his life – and the lives of the people he loves – for the better, or will he just make things worse?

Sheen, a true chameleon in everything he does, tells us about the unique challenges in playing a character through different parts of both his life and time frames and how he navigated it, as well as the lure of such a larger-than-life man that has somewhat lost his way. Emmanuel, meanwhile, tells us about being drawn to Sue and her story, working alongside Sheen, and the misconceptions of the character that many will have when they first meet her and where her own journey goes.

And, of course, favorite Christmas songs. Rude not to…
