Maggie Gyllenhaal spoke about the joys of working with Channing Tatum and Jamie Foxx in White House Down recently when we caught up with her in Washington DC. With the real White House just one block behind her, Maggie told us about playing a Secret Service agent who decides not to hire Channing's character. She revealed her backstory with Jamie too, having known him since 2005 when he made Jarhead with her brother, Jake, and her husband, Peter Sarsgaard. Plus, Maggie touched on how she plans to spend the Summer with her two young daughters.">
