Set in Los Angeles in 1962, at the height of the Cuban missile crisis, "A Single Man" is the story of George Falconer, a 52 year old British college professor (Colin Firth) who is struggling to find meaning to his life after the death of his long time partner, Jim (Matthew Goode). George dwells on the past and cannot see his future as we follow him through a single day, where a series of events and encounters, ultimately leads him to decide if there is a meaning to life after Jim. George is consoled by his closest friend Charley (Julianne Moore), a 48 year old beauty who is wrestling with her own questions about the future. A young student of George's, Kenny (Nicholas Hoult), who is coming to terms with his true nature, stalks George as he feels in him a kindred spirit. "A Single Man" is a romantic tale of love interrupted, the isolation that is an inherent part of the human condition, and ultimately the importance of the seemingly smaller moments in life.

Tom Ford's directorial debut.
Despite having produced many movies, this is the first time Chris Weitz has worked as a producer on a feature film, without his brother Paul Weitz's involvement.
Victoria Silvstedt auditioned for a role.
Colin Firth was originally not available for the role and someone else was cast. Then there was a shift in the movie schedule and Firth was eventually able to take the part.
Tom Ford revealed in an interview that the role of Kenny was originally given to a more famous actor who then didn't show up to the costume fitting five days prior to shooting. Ford then remembered an audition tape by Nicholas Hoult.
The production design was done by the same team that created the production sets in Mad Men, which is also set in the sixties.
The film premiered on September 11, 2009 at the 66th Venice International Film Festival and was nominated for the Golden Lion. Colin Firth was awarded the Coppa Volpi for Best Actor at the film festival for his performance in the film.
