I'm one of those people that would have never read "A Single Man" if it weren't for Tom Ford and Colin Firth. To be truly honest, I think I'd rather watch the film again than reread the book (despite some changes in the film version), and that's mostly for the incredible cinematography, the stunning interiors and have you noticed how awesome Colin looks in those suits?
However, one year apart, I've totally forgotten one important detail: everything happens in an ordinary, augmented day. To an (extra?)ordinary, most profound and honest man you can't help but love.
