Here's a good excuse for philandering: "I sleep with other women because I'm a poet, and a poet feeds off life!"
That's Dylan Thomas talking - Dylan Thomas as played by Matthew Rhys in the insufferable The Edge of Love, a stagy, arty, and uncompelling account of the Welsh writer and his menage-y relations with his boozy Irish wife, Caitlin (Sienna Miller), and his young Welsh girlfriend, Vera Phillips (Keira Knightley).
Set during the London Blitz and the tumult of World War II, John Maybury's overly art-directed drama pivots around a real scandal in Thomas' life. A decorated British soldier by the name of William Killick (Cillian Murphy), returns from the front to find his wife - yes, Vera - romping around with the poet and his wife, apparently living off, and drinking through, Killick's savings. The good captain, possibly suffering post-traumatic stress syndrome, or maybe just peeved, fires his machine gun in the general direction of Thomas. A trial ensues.
