Actor Timothee Chalamet made a surprise appearance at his own look-alike contest in New York on Sunday, a well-attended event that drew an order to disperse from police and saw at least one arrest. Flanked by bodyguards, Chalamet posed for photos with his look-alikes, some of whom had dressed as Willy Wonka and Paul Atreides — characters that Chalamet has played in Wonka and the Dune movies. At times, adoring fans heaped their attention on the look-alikes, apparently thinking they were face-to-face with the real Chalamet.

At least one contestant was taken away in handcuffs, though police did not immediately say why. “It started off as a silly joke and now it’s turned pandemonium,” said Paige Nguyen, a producer for the YouTube creator.

Most of the wannabe-Chalamets and spectators relocated to a different park. On a makeshift stage, the look-alikes were asked about their romantic plans with Kylie Jenner. Jenner and Chalamet are said to be a couple.

They were also asked to demonstrate French proficiency and what they would do to make the world a better place. Eventually, the audience picked a winner: Miles Mitchell, a Staten Island resident and student. Dressed in a purple Willy Won.
