Late September (15)

Jon Sanders's slight but absorbing ensemble drama examines the tensions and antipathies swirling just beneath the convivial surface of a small birthday celebration.

Ken (Richard Vanstone) and Gillian (Anna Mottram) are bickering to the end of a calcified 40-year marriage. Meanwhile, Ken's best friend, Jim (Bob Goody), tries to roll back the years with a younger party guest on his boat, moored nearby.

Sanders frames scenes in the meticulous manner of fellow Brit Joanna Hogg, though the digital video on which he shoots looks too harsh for his watercolour intimacies.

The script, entirely improvised by the cast, strikes resonant chords of late middle-aged angst.
