Sundance's Very Good Girls Is a Family Reunion For Jake Gyllenhaal and Peter Sarsgaard

Jake Gyllenhaal stepped out to support mom Naomi Foner, the screenwriter behind Very Good Girls, at the film's Sundance Film Festival premiere last night. He was joined by brother-in-law Peter Sarsgaard, who's married to Maggie Gyllenhaal and also stars in the picture. It was an extra busy night for Peter, since he also debuted Lovelace with Amanda Seyfried. Very Good Girls leading lady Dakota Fanning attended the screening at the Eccles Center theater and later on linked up with her and Peter's costar Elizabeth Olsen at an afterparty. Jake made the rounds with his pal Jenny Lewis. He looked good while doing so — Jake has a new look, with slicked-back hair, for a new project. He's been in Georgia making Prisoners with Hugh Jackman.
