Llyr Evans, Rhys Ifans

An unlikely but wildly enjoyable hybrid, this Welsh comedy combines the dopey humor of Wayne’s World, the doped-up chic of Trainspotting and, oddest of all, the sort of spectacularly violent revenge ethic that one associates with those unforgiving Corleones. Filmed in Swansea in South Wales, Twin Town takes place in a loud, tacky world of trailer parks, massage parlors and karaoke bars. Teenage twins Julian and Jeremy (non-twin brothers Evans and Ifans, the latter using the Welsh spelling) spend their days hot-rodding cars, dealing drugs to senior citizens and hitting ye old bong. When their father, a handyman, is injured doing roofing work, the contractor refuses to pay his insurance and the twins decide to mete out their own brand of justice. There’s no point giving away any more of the plot beyond that, except to say that a poodle named Fergie pays a terrible price. (Not rated)
