Colin Firth has joined World War Two veterans and the widow of the man he plays at the premiere of The Railway Man.
He portrays Eric Lomax, a soldier who was tortured at a Japanese labour camp during the war.
Decades later Mr Lomax came face to face with one of his captors and wrote about his experiences in a memoir, upon which the film is based.
Eric Lomax died before the movie was finished but was fondly remembered on the red carpet.
