The contest, organised by YouTuber Anthony Po, promised a $50 (£39) prize for the winner and had attracted thousands of RSVPs to an online invite.
A fan of the Call Me by Your Name and Dune actor, Lauren Klas, described what made a good Chalamet. “It’s all in the nose,” he told AP news agency.
“All of his bone structure, really.”
Contestants were also asked about their French language skills, plans to make the world a better place and romantic intentions with Kylie Jenner, who the star is rumoured to be dating, AP reported.
Eventually Miles Mitchell, 21, from Staten Island, was crowned winner dressed in a Willy Wonka outfit, before he tossed candy to the crowd from a briefcase.
