Set during WW2, the movie follows the story of British officer Eric Lomax as he is captured by the Japanese and sent to a POW camp where he's forced to work on the Thai-Burma railway. Moving around in time, Colin plays the older Eric, while Eric during the war is played by actor Jeremy Irvine.
After the war, Eric's wife Patti (Nicole) encourages him to face one of his captors to try to gain closure on his experiences.
Colin and Nicole were spotted filming on set at a train station. They were later out at a press conference to help promote the movie.
