Geoffrey Rush’s retired judge is terrorised by Lithgow’s therapy puppet-wielding fellow resident in this claustrophobic tale of elder-on-elder abuse

Film-maker James Ashcroft has created a scary and intimately upsetting psychological horror based on a story by New Zealand author Owen Marshall set in a care home, a film whose coolly maintained claustrophobic mood and bravura performances make up for the slight narrative blurring towards the end. It’s a movie about bullying and elder abuse – more specifically, elder-on-elder abuse – and it is always most chilling when it sticks to the realist constraints of what could actually happen.

The locale is an un-luxurious residential care facility where a retired judge is now astonished to find himself; this is Stefan Mortensen, played by Geoffrey Rush, who succumbed to a catastrophic stroke while passing judgment from the bench. He is a cantankerous and high-handed man, furious to be in this demeaning place and who, like many there, assures himself it isn’t for long. Mortensen has to share a room with Tony Garfield (George Henare), a retired rugby star whose career fizzled out. These men are terrorised by long-term patient Dave Crealy, played with true hideousness by John Lithgow, a racist bully who convinces the care staff he is a gentle, harmless soul by exaggerating his mental and physical decay, but tyrannises patients behind officialdom’s back with his therapy hand puppet named Jenny Pen, making the bewildered and terrified patients submit to her “rule”.
