Timothée Chalamet: how the prince of indie grew into a multiplex star

A role in the sci-fi epic Dune has transformed the young actor into a bona fide leading man - but not one from the old Hollywood mould

In September, the Met Gala in New York - Anna Wintour's annual fusion of fundraising gala and celebrity parade - redesigned itself for generation Z. Instagram sponsored the event, Justin Bieber was its headline performer, and four young whippersnappers were enlisted as co-chairs: singer Billie Eilish, tennis player Naomi Osaka, poet Amanda Gorman and - the elder statesman of the quartet at 25 - Timothee Chalamet.

Chalamet turned up, typically tousle-haired and puppy-eyed, in an outfit of two halves. Up top, a cropped, snugly tailored satin tuxedo jacket by avant-garde designer Haider Ackermann, complete with cummerbund and blingy brooches. Below, a pair of baggy cream jogging bottoms, tucked into white socks and Converse trainers. Half princely film star, half kid at play: it's a look that encapsulates the persona of the biggest, most hysterically obsessed-over teen idol to emerge from the movies since the heyday of Twilight.
