Resnais blurs the lines between theatre and cinema in this mature treatise on the ‘love triangle’, marked by a trio of outstanding performances. 

Resnais’ tonally-jarring ‘musical-drama’ that intercuts across three timelines feels too artificially-constructed and incoherent to make any meaningful sense.

An unexpected critical success, Resnais’ sly, mosaic-like film about behavioural psychology as explored through the personal stories of a trio of interconnecting characters is a masterclass in associative editing, and one of his finest pictures.
