One of the many films to premiere at Sundance this year was writer-director Naomi Foner’s Very Good Girls.  The film stars Dakota Fanning and Elizabeth Olsen as two lifelong best friends that fall for the same boy during a New York summer.  As the film unfolds, they learn life isn’t as simple as they had thought.  The cast also includes Boyd Holbrook, Demi Moore, Ellen Barkin, Richard Dreyfuss, Peter Skarsgaard, and Clark Gregg.

Earlier today I sat down with Dakota Fanning and Elizabeth Olsen here in Park City.  We talked about being back at Sundance, how much changed during production, the type of research they do for a role (Fanning tells a great Tony Scott story), how many takes they like to do, whether they like watching themselves on screen, and a lot more.  In addition, when talking about future projects, Fanning revealed she’s been cast in The Last of Robin Hood which is about the last two years of Errol Flynn’s life (Kevin Kline is playing Flynn).  Hit the jump to watch.

A few big names in today’s casting round-up:

• Matt Damon (Good Will Hunting) is set to re-team with The Brothers Grimm director, Terry Gilliam, for a small role in his upcoming film, The Zero Theorem.
• Kevin Kline (The Ice Storm) is set as the lead of Errol Flynn in Quinceañera directors Richard Glatzer and Wash Westmoreland’s indie, The Last of Robin Hood.  Susan Sarandon (Thelma & Louise) will co-star.

Hit the jump for much more on both films.
