The latest trailer for Keira Knightley’s 27th consecutive period film, THE EDGE OF LOVE, has recently made its way online. In it, she stars as the real life love of poet Dylan Thomas’ life. The only hitch is that he happens to be married to Sienna Miller and she eventually marries a soldier (Cillian Murphy) and when he finds out his brand new wife and Thomas have been doing the ole rough and tumble, he shoots the shit out of Thomas’ house. Of course things are a lot more emotional and complex than that. Click through to check out the trailer and get it in HD over at Moviefone. The movie was released in the UK in June of last year but will finally be making it stateside on March 13th. Below you’ll also find the film’s poster.
