Directed and co-written by fashion designer Tom Ford, the film is his directing debut and shows a polished end product which utilizes the rich narrative and actors performances over technical production elements to engage the audience for the entire 1 hour 39 minutes. The only additional element that Ford utilizes in the mesmerizing music of Abel Korzeniiwski which almost becomes an additional character by its haunting presence throughout the movie.
The most simple and possibly under valued scene in A Single Man is when George sees a dog in a car at the supermarket similar to the two dogs that he lost in Jim's accident. Jim was found with the male dog, but the female dog was never found. The dog George is now seeing is a female. The owner returns and George lingers at the car to the point of awkwardness. This simple throwaway scene is given an immense impact thanks to Colin Firth's performance.
A Single Man is a film which shows how story can exist on its own without the need for special effects as enhancement or hindrance. This is the sort of filmmaking that the world needs more of but unfortunately is in short supply.
