You might say Dennis Villeneuve’s adaptation of Frank Herbert’s novel plays like ponderous messianic nonsense and write an obituary for blockbusters when you stream this on HBOmax, but you haven’t really lived until you’ve watched Timothée Chalamet projected 100 ft tall, popping his head out of a sand dune like a floppy-haired prairie dog. Sure, Dune has it’s premiere-premiere in Venice last week (and seems to have screened for select critics elsewhere), but they granted Toronto the honors of hosting the film’s international IMAX premiere.
