The Card Counter (2021, Paul Schrader) 9pm, Film4
Oscar Isaac stars as another of writer-director Paul Schrader’s self-contained, self-sufficient loners in this 2021 morality tale. William Tell is an expert card player who travels around the casinos of the US, winning just enough to make a living but not so much that he draws undue attention. When he meets Tye Sheridan’s rootless youngster Cirk, who has a link to William’s dark past in the military, a hint of fellow feeling appears. Tiffany Haddish, as an agent for top poker players, adds another entanglement, as William tries, belatedly, to do some good in his life. Simon Wardell
