Stars snap portraits at the Producers Ball while the 'Sicario' cast partied at Soho House

It was a starry night at the Royal Ontario Museum for the 5th annual Producers Ball, a fête hosted by the perpetually loveable Property Brothers, Drew and Jonathan Scott. But it wasn't all fun and games, despite the play that went on at the Twitter TV station and the 3D virtual orchestra installation, as money was raised to benefit TIFF's industry and filmmaker development programs.

The red carpet proved a who's who of Canadian talent, from Emmy nominee Tatiana Maslany to Baywatch icon Pamela Anderson (with her son in tow), and famous faces like Suits star Patrick J. Adams, Lauren Holly, Torrance Coombs and Dan Levy stopped by Hello! Canada's portrait studio to have their mugs shot by celebrity photographer George Pimentel.

Dan, clad in a dapper blue suit, crossed paths with fellow Hello! hottest bachelor Jonathan Scott, who posed for a selfie with his brothers. And as the night raged on, ballerinas bedecked in macaron-clad umbrellas circulated while guests nibbled Purdy's chocolates, knowing that their silent auction bids and raffle tickets would help keep TIFF one of the most exciting festivals in the world.

Pamela Anderson and her son celebrated the festival.

Farther downtown at the Grey Goose Soho House was a splashy affair for the cast of the well-received Sicario, a tense drama helmed by Canadian visionary Denis Villeneuve.

Emily Blunt was radiant in a periwinkle-blue, strapless tea dress by Dior Couture and the best accessory of all - husband John Krasinski, who's been making the rounds with his leading lady in support of her latest hit (do we smell Oscar buzz?). Hamming it up with male co-stars Benicio Del Toro and Josh Brolin, the new mom and newly minted American citizen looked radiant as ever.

Rachel McAdams looked gorgeous in a black strapless gown.

And speaking of radiant, Every Thing Will Be Fine star Rachel McAdams is back on the Toronto red carpet, having premiered her last flick, Southpaw, at the Scotiabank Theatre just two months ago. The actress, who is also debuting Spotlight at the festival, hit the Mongrel House after last night's premiere to celebrate. Fellow actors Geoffrey Rush and Michael Shannon (at TIFF to premiere Freeheld) were also in attendance.

And over at the Shangri-La, surprise festival guest and recently self-proclaimed "arm candy" George Clooney had his own celebration.
