Brittany Snow goes back to her blonde locks at the premiere of Petunia during the 2012 Outfest held at The Director’s Guild of America on Saturday night (July 14) in West Hollywood, Calif.

The 26-year-old actress plays Robin in the upcoming film about a dysfunctional family unit on the verge of a nervous breakdown.

Petunia weaves together the lives of brothers Charlie (Tobias Segal), Adrian (Jimmy Heck) and Michael (Eddie Kaye Thomas) as they unlearn everything their psychoanalyst parents have taught them. While Michael’s cynical wife Vivian (Thora Birch) discovers she is pregnant, the family is also changing.

Charlie’s would be boyfriend George (Michael Urie) is in a polyamorous relationship with fitness fanatic Robin (Snow) and Adrian has developed a unrelenting sex addiction.
