Mother Joan of the Angels (Jerzy Kawalerowicz, 1961). Starker and more cerebral than Ken Russell’s The Devils, to which it could be an unofficial sequel, but made a decade earlier. Don’t look for Poland-under-communism metaphors either. Long exorcism scenes are the centrepiece, and some of the possession actions suggest that William Friedkin was paying attention – but again, so much less lurid. At its heart, there are theological questions – how does love find expression when it’s suppressed or thwarted?
