Hello! Canada House celebrated 'Green Room' while Jake and Naomi partied for 'Demolition'

On the hotly anticipated opening night of the 40th Toronto International Film Festival, the red carpet was rolled out outside of the iconic Storys building, where onlookers clamoured for a peek at the glamourous stars arriving at the official Hello! after-party for Midnight Madness thriller Green Room. Director Jeremy Saulnier — an early arrival — posed for photos and greeted the film's stars, Anton Yelchin and Imogen Poots (get Imogen's chic red-carpet look here!), as they made their way inside. Jeremy, sporting a slim-fitting grey suit, mingled with guests who were anxiously awaiting the midnight screening of his latest horror-thriller about a punk rock band in Oregon that gets tangled in a murderous scene backstage after a show.

Anton, the film’s phenomenal lead, worked the room and shared laughs with his co-stars, his hair tousled in perfect punk rock form (he does play a bassist, after all). As the music blared and the night carried on, there was a flurry of flashing lights and commotion as Sir Patrick Stewart arrived in time for a cast photo-op. The legendary actor was his typical gregarious self, moving through the crowd with the kind of ease and familiarity that drew admirers from around the room. Meanwhile, the adorable Imogen momentarily slipped away from the A-list action for a wholesome snack at the Metro fresh bowl bar. Then, before the stroke of midnight, the excited crowd made their way to the Ryerson Theatre, just in time to catch the 12 PM screening.

A little ways down at celebrity-favourite Patria, heavy hitter Jake Gyllenhaal was the talk of the room. After sharing a cute KFC anecdote on the red carpet and screening his latest, Demolition, courtesy of Canadian filmmaker Jean-Marc Vallée, the actor sidled up to co-star Naomi Watts, resplendent in an undulating swath of blush-hued Balmain, and the two shared a Grey Goose cocktail and a rug, which they cut with gusto to Drake ditties. Compared to in-theatres Everest, in which the famously versatile actor tackles the famed mount, mingling seemed a breeze for Jake, who looked dapper as ever in a charcoal suit and burgundy tie. Speaking of dapper, Mad Men creator Matthew Weiner was also in attendance, as was director Jason Reitman — who is staging a live reading of The Princess Bride on Sept. 12 at 6 PM.

Over at the Trump, Toronto Life held its annual Best Dressed event, toasting the city's most stylish in a swank shindig. Spanning multiple floors, guests got the star treatment, from fresh juices to natural beauty products, shoe shining and Swarovski-inspired macarons - plus the Broadway-worthy sign that spelled out the publication's name. A wall of balloons celebrated listees, among them cover girl Shay Mitchell and one of Hello!'s 25 hottest Canadian bachelors, Dan Levy.
