IT won't be released in U.S. theaters until 2009, but the DVD of The Edge of Love, a film about the life of Welsh poet Dylan Thomas starring Keira Knightley, Sienna Miller, Matthew Rhys and Cork's Cillian Murphy, will be out in the U.K. at the end of the month.

With such a stellar cast it's surprising that the American market won't get a look until next March, when the film is tentatively scheduled for release here. Knightley's mother Sharman MacDonald wrote the screenplay, inspired by the love letters that Thomas sent to his wife during World War II.

Knightley plays Vera Killick and Murphy portrays her husband William. Thomas (Ifans) is in love with Vera and also his own wife Caitlin, played by Miller. "The story explores the bohemian underworld of war-torn London and the intimate complexities of two young couples whose lives and loves become dangerously intertwined," says a release from the U.S. DVD distributor, Image Entertainment.

In case you're interested in a sneak preview of a sex scene between Murphy and Knightley in the movie, the ever-reliable British tabloid News of the World has one. Go to www.notw.co.uk and you'll see it flagged on the home page.

Murphy's career in the U.S. had really taken off a few years back with his starring roles in Batman Begins and Red Eye, and of course there was his starring role in The Wind That Shakes the Barley in 2006 which won the top award at the Cannes Film Festival, but he hasn't done much of note lately. A film he shot with Lucy Liu last year, Watching the Detectives, went straight to DVD over the summer, but the IMDB movie website says he has a number of projects in pre-production.
