If the just-released trailer for Angelina Jolie’s directorial debut, Unbroken, is anything to go by, the film is going to be unbelievably good.

The moving two and a half minute clip grabs you with both hands. Watch below, and then mark the film's release date in your diary.

Unbroken is based on the extraordinary true story of Olympic runner Louis Zamperini ‘a rebel who became a champion.’ He miraculously survived on a raft at sea for 47 days, after a plane crash in WW2 – only to be caught by the Japanese Navy and sent to a prisoner-of-war camp.

English actor Jack O’Connell (recognise him as Cook from Skins?) plays Louis in the film. This teaser glimpse of his performance promises great things and the cast also includes About Time star Domhnall Gleeson and On The Road’s Garrett Hedlund.

Unbroken is in cinemas on 26 December
