National Theatre Wales and Told by an Idiot bring their critically acclaimed celebration of Gwyn Thomas – one of the most distinctive Welsh voices of the last century – and an outstanding Welsh cast to the Edinburgh Festival. Taking as its inspiration Thomas' ink-black comic tales, The Dark Philosophers is a funny, violent and passionate depiction of a community teetering on the brink of humanity. Using Told by an Idiot's trademark anarchic physicality and inventive storytelling, this adaptation brings out the bleak, wild humour in tales laced with sex, murder and Thomas' devastating Valleys wit.
