Compare how vital Kelly Macdonald was to 1996’s Trainspotting with her cursory presence in 2017’s boysy sequel, and you’ll have some sense of how the British film industry has underestimated her. Macdonald has always been a supremely sympathetic performer, but her mousy air may have been seen as a big-screen limitation. She scuttled round in subservient roles, before escaping pantry duty via HBO’s Boardwalk Empire: a wife part, yes, but one that proved steelier than first imagined over that five-season run. TV arcs bend towards their own form of justice.
Puzzle, the offbeat Us indie opening this year’s Edinburgh film festival, finds Macdonald tending house yet again – though here it’s an acknowledgement of wasted potential, a corner from which her character Agnes needs to be sprung.
