Colin Firth couldn't let go of his 'A Single Man' character George Falconer.
The 49-year-old actor - who plays the role of a gay English professor who is grieving for his recently deceased partner - admitted the emotional role got under his skin.
He said: "I dare say there is something of me in the role because it's one of those rare experiences as an actor where you walk off the film set and can't quite shake it off and that went on for months.
"But, you know, at the same time it's a very comprehensive job of work for me to do because it's one day in the life of a man who - in a very quiet way - goes through just about every emotion I can think of."
The British star was delighted to take part in the Tom Ford-directed movie because it was a good opportunity for him to play a leading man.
He added to website Digital Spy: "I can't think of the last time I was actually in the position of carrying a film, you know? Or being put right at the heart of a film. It's really very rare that I get that opportunity and I'm satisfied that, obviously having been given that opportunity, it seems to have come out so well."
