The Sundance Film Festival is coming to an end on Sunday with Ashton Kutcher's jOBS premiere closing out the festival tonight, but there's already been plenty of action.

Earlier in the week, Jessica Biel posed with Emanuel and the Truth About Fishes costars Alfred Molina, Kaya Scodelario, and director Francesca Gregorini at a party while Jake Gyllenhaal flew in to support his mom Naomi Foner's directorial debut, Very Good Girls.
