In Martin McDonagh’s latest dark fable, friends become separable on an island off Ireland small enough to not be able to avoid each other. Day after day Pádraic (Colin Farrell) and Colm (Brendan Gleeson) meet at the pub and chatter inanely until all at once Colm decides life is too short and he should be focussing his remaining years on artistic fulfilment. Confused and hurt, Pádraic persists until Colm makes a gruesome threat that changes their relationship dynamic irrevocably. Being a McDonagh joint, this is pretty bleak, existential stuff, but it’s also really funny with moments of gallows humour and absurdist comedy coming from Farrell (in his best ever lead role), Kerry Condon, Barry Keoghan and a scene-stealing donkey. It’s also a film of depths, of small details coming from its setting (Civil War Ireland) and illusive meanings to decode from its maybe-supernatural elements. SSP
