Fabelmans, 9.15pm, Channel 4

Steven Spielberg mines his own history for his most personal film yet, a 1950s drama about family, growing up, and the power of cinema. The film revolves around Sammy Fabelman (played by Gabriel LaBelle as a teenager), who becomes obsessed with filmmaking at a young age and continues to pursue his cinematic dream as the family moves from New Jersey to Arizona to California. Despite the nostalgia for the post-war era of opportunity, there is also anti-Semitism – and internal turmoil between his very different parents (Michelle Williams and Paul Dano). Simon Wardle
