That was the only time Tom Ford had to get on my case because I was supposed to be playing a gay man and he told me to keep my hands to myself and keep my tongue out of her mouth." Colin Firth couldn't hide the fact he enjoyed kissing co-star Julianne Moore in his new film A SINGLE MAN - despite playing a homosexual professor.
