Dougray Scott has insisted he did not get cabin fever filming in a train carriage for 26 days straight.
The Scottish actor appears opposite Kara Tointon in thriller Last Passenger about a group of commuters trapped on a speeding train, whose driver is on a crazed mission. The low-budget British indie film was shot in two train carriages in just 26 days.
Dougray said: "The confines of the space, I think it really helped shooting the scenes, because the more you are on the train the more you want to get off and you can't get off because that's where you're filming. So it really helped tell the story."
He added: "You finish filming one day and you come in the next day and you jump straight back into it. I think the short film period actually helped, you've got that sense of adrenaline anyway, because you've got very little time to film it.
The 47-year-old actor - who was once rumoured to be in the running to play James Bond - also confessed he preferred shooting the dialogue scenes about a mundane commuter journey to the action scenes.
He said: "I liked the stuff at the beginning. The action stuff at the end was fun, but doing all that stuff at the beginning was nice and gentle."
The father-of-two also said he liked to think if he was in the same situation he would follow his character in leading his fellow passengers in a fight for freedom.
Dougray said: "I think if I was with my son or daughter on the train I would be a leader because I would do everything I could to save their lives. You never know until you're in the situation. Would I be calm about it? I don't know. I'd certainly try my damnedest to save them and to try and get out of the situation."
