At the same time CAA threw its annual Toronto Film Festival party Sunday — with guests Naomi Watts, Chris Evans and Colin Firth, and what another guest called “VIP areas within VIP areas” — Bill Murray partied somewhere less snooty, at the epically titled Bovine Sex Club. The actor incongruously emerged from a back room at the decrepit den as a mass of mostly young Euros danced to the Cure under what must’ve been the world’s smallest disco ball. The bash was hosted by Switzerland’s Locarno Film Festival, and Murray was seen following an attractive woman in a cocktail dress through the crowd and out the door, after mingling in a back room. A night later, Murray showed up at the premiere of Focus Features’ “Hyde Park on Hudson” with loose Twizzlers in the breast pocket of his suit jacket. He also gamely posed for pics on the red carpet with a doll of the Stay Puft Marshmallow Man from “Ghostbusters” that a fan handed him to sign. After hitting a dinner for his film with Laura Linney, Murray mixed at Grey Goose’s Soho House after-hours party.
