Leonardo DiCaprio and Anne Hathaway Party at Soho House During the Toronto International Film Festival

Environmental advocate and actor Leonardo DiCaprio stopped by the Toronto International Film Festival on Friday afternoon to premiere his highly anticipated documentary Before the Flood. From Oscar-winning producer Fisher Stevens (The Cove), Before the Flood follows DiCaprio as he traverses the globe—interviewing President Barack Obama, Bill Clinton, and John Kerry along the way—to bear witness to the widespread environmental destruction brought about by ignorance or, worse, apathy.

After the film’s world premiere at the Princess of Wales Theatre, the Revenant star headed to Soho House Toronto with filmmaker Brett Ratner, actor Leon Robinson, and the National Geographic team in tow. Standing by the club’s signature wall-mounted moose head, DiCaprio raised a glass to the doc’s success, which will hit L.A. and New York on October 21 and then air on the National Geographic Channel. Guests at the intimate after-party sipped on Grey Goose cocktails before clearing out for the Colossal fete held later that evening.

The Soho House’s late-night crowd included Colossal’s Anne Hathaway, Jason Sudeikis, Tim Blake Nelson, Austin Stowell, and director Nacho Vigalondo, who all mingled among partygoers with a refreshing, approachable air. Hathaway, the film’s leading lady, was all smiles in a Givenchy jumpsuit, and later she opted to ditch her heels. A pregnant Olivia Wilde supported fiancé Sudeikis with an impressive post-midnight showing, before waving goodbye to Hathaway, who held down the lively soiree well into the evening.
