This film, part of the Walerian Borowczyk season at the BFI, also screens on May 20. Details here.
Here is the BFI introduction: A petty thief works his way up the absurd hierarchy of Goto, an archipelago cut off from civilisation by a tumultuous earthquake. His dream is to possess Glossia, a stifled beauty trapped in a loveless marriage to a melancholic dictator. Originally banned in Communist Poland and Franco’s Spain, Goto, Island of Love features bizarre sights, poetic flashes of colour and the stunning deployment of Handel’s organ concertos.
Here (and above) is the opening.
