Fashion designer Tom Ford is ready to delve into new territory: filmmaking. Allies he already has, as Colin Firth, Julianne Moore and Matthew Goode will be starring in his directorial debut, “A Single Man.”

The indie drama will be Tom Ford’s adaptation of the Christopher Isherwood novel of the same name, published in 1964. It tells the story of George, a middle-aged gay man who has recently and suddenly lost his longtime lover.

Variety reports that Colin Firth is set to portray George, who is an Englishman and works as a college professor in Los Angeles, while Matthew Goode will portray the deceased lover, Jim, appearing in flashbacks. Julianne Moore will play a friend of the professor’s. The film will show one day in George’s life.

Ford adapted the screenplay with David Scearce. The project is being financed independently. Filming is scheduled to begin in Los Angeles next week.

Tom Ford was creative director at Gucci for a decade, becoming a bona fide star of the fashion world. He stepped down in 2004 and formed Fade to Black in 2005, as well as his own fashion company.

Colin Firth starred earlier this summer in the stage-to-film adaptation “Mamma Mia!,” alongside Meryl Streep, Pierce Brosnan and Stellan Skarsgard. Julianne Moore was recently seen in the thriller “Blindness,” opposite Mark Ruffalo. Matthew Goode plays Ozymandias in next year’s “Watchmen.”

Ford is reported to be collaborating with the production designers of AMC’s series “Mad Men,” which happens to be set in the 1960s, just like Christopher Isherwood’s novel.
