Jake Gyllenhaal and Naomi Watts dance to Drake at the Demolition premiere

Last night, as guests piled into the the King West resto-lounge Patria to fête TIFF’s opening-night film Demolition, the first thing they saw was director Jean-Marc Vallée greeting friends with a kiss on both cheeks, speaking in rapid-fire French. The party had a festive air, with the film’s stars Jake Gyllenhaal and Naomi Watts sipping customized cocktails by the party’s sponsor Grey Goose, munching on lobster croquettes with caviar and dancing to Drake remixes.

Gyllenhaal spent the rest of the party deep in conversation with producers while the rest of the partygoers tried to harness their courage to talk to him. He was pulling a party manoeuvre known as the “kiss-the-ring” move: he simply stayed at his post and made the rest of the crowd come to him. He gesticulated wildly with his hands while he was talking, wore an incredible grey suit and seemed happily oblivious to the crowd of onlookers.

Watts, looking like a tiny, expensive bird in an effervescent pink ruffled dress, air-kissed producers, threw her arms around a male friend, and seemed generally cheery and luminous. Director Jason Reitman appeared for five minutes and escaped with a female friend out the back entrance after greeting local child actor Gage Munroe (who will take on the young Fred Savage’s role in Reitman’s Princess Bride live read tomorrow). After an hour, the celebs left and the mood quickly shifted to a more dour, clubby vibe.

Also in attendance was Mad Men showrunner Matthew Weiner, who had just flown in for a special event where he provided live commentary on the show’s season one finale. On the subject of his post–Mad Men career, Weiner said he is figuring out a few ideas but not working on anything right now. But was he having a good TIFF? “I’m just in town for one night,” he said. “It’s great.”
