The gala presentation of Butter at Roy Thomson Hall last night was all about the ladies. Little Yara Shahidi kicked off the proceeds at the most packed and frenetic red carpet since Madge walked here on Monday, and she was downright adorable, giggling at the barrage of flashes and the demands of fans who claimed to have been lining the barricades since 5 a.m. Ashley Greene came next in a swish knee-length silver number, but was—dare we say it—outshone by Olivia Wilde, who was stunning in a floor-length white and gold gown (we’re not sure if it was intentional, but she did appear to be channelling Diane Kruger’s character in Troy). The only fellas worth mentioning at this affair were director Jim Field Smith and writer Jason Micallef. Sadly, Hugh Jackman couldn’t make it to the Big Smoke for this year’s festival, but Alicia Silverstone helped make up for it, although we figure it must be annoying to still be signing eight-by-10s of herself as Cher Horowitz from Clueless. Of course, Jennifer Garner also graced the red carpet, sporting two of this year’s most popular accessories: epically high heels and a baby bump. See our photo gallery, after the jump.
