Anna Kendrick and former Twilight costar Rachelle Lefevre get the giggles as they feed a goat and attend The Men Who Stare At Goats premiere party held at the Glaceau vitaminwater house during the 2009 Toronto Film Festival in Toronto on Friday night (September 11).

The 24-year-old actress, who was there to support costar George Clooney, stepped out at TIFF this afternoon (September 12) to premiere her own flick, Up In The Air at the Ryerson Theatre.

Anna plays Natalie in the upcoming dramedy about Ryan Bingham (Clooney), a corporate downsizing expert whose cherished life on the road is threatened just as he is on the cusp of reaching ten million frequent flyer miles and just after he’s met the frequent-traveler woman of his dreams.

The Up In The Air premiere date just got moved up! It now opens in theaters over Thanksgiving weekend, on Friday, November 25th.
