Twin Town (1997)

With Trainspotting's Danny Boyle and Andrew Macdonald as executive producers, Kevin Allen's Swansea comedy follows the Lewis brothers, a pair of joyriding hustlers known as the twins, as a feud with a local big shot spirals out of control. Rhys Ifans plays one brother opposite his real brother, Llyr, credited as Llyr Evans. It is crude, profane and far rougher than its stablemate, and it drew criticism for its swearing and for how Swansea looked on screen. That is part of its value now: its anarchic energy catches a strand of the decade, small-town, Welsh and broke, that the London films never touch.
