The action’s up here, people! InStyle is in Canada for the annual Toronto International Film Festival, where we set up a purple-walled and zebra rug-covered pop-up portrait studio in the Windsor Arms Hotel so some of our famous friends can come say hi. “I was here for the first time five years ago for Juno, and the feeling then was really special because here was where everyone realized it was going to be something big,” said Olivia Thirlby of Dredd 3D, who trotted into our studio first wearing a ladylike Kate Spade outfit. “This year, it feels kind of similar.” It’s a special feeling all around, more celebrities told us as they passed through, like the Argo cast (including director and star Ben Affleck, who picked up pal Matt Damon’s water.org filtered water bottle), and Mad Men‘s Christina Hendricks, wearing a fitted Bird jumpsuit to promote her new flick, Ginger & Rosa. And it’s only getting started! See more photos and get all the behind-the-scenes dish from straight from Toronto in the gallery.
