When reports started to emerge that Timothée Chalamet was going to play a ping pong champion in a film called Marty Supreme, the world (including this correspondent) rolled its eyes. Was Hollywood’s most annoying actor going to go for broke in what promised to be the most irritating film of all time? Well I am here to hold up my hand and say that first impressions couldn’t have been more wrong. Marty Supreme is one of the most exciting, indeed sensational films of the year, and if the Guardian film critics’ poll wasn’t a democracy, many of us would made it No 1 by some distance.
