an odd and willfully skew biopic of dyan thomas in which we hear little more than a dozen line of his poetry . instead we have to endure a raw character exposée see through the prism of his proto bigamous relationship with wife ( sienna miller ) and childhood love ( keira knightley ) . matthew rhys play thomas with sufficient charm to inoculate u against his otherwise repellent self interest and cillian murphy make up the persistently tense lovetet . the film never seem to decide on where it go . there no arc so much a a viaduct from one end of the war to the other . maybury seem much more interested in his two female lead ( who wouldn not . ) than in the man who bring them together and then divide them . miller be the choice of the two ( i find knightley competent at best but then i have never find her sympathetic ) but they both offer dreadfully inconsistent welsh accent . other funny decision include too much for the inconsequential character of william ( murphy ) and arty production ( eg double crossfades ) that be neither impressionist nor symbolic and the old chestnut act of period footage which doesn not blend . 4/10 .
