Like the British actor who starred in so many films in so little time that Chris Rock teased him about it at the Academy Awards, the 28-year-old actress Maggie Gyllenhaal suddenly has five movies hitting theaters in just three months. "I didn't make them all at once," she says, laughing, propping her bare feet on a chair as she sips a glass of orange juice. "I made them over 2 1/2 years, but it's actually kind of interesting to see all my work over that time come out at once." But "Sherrybaby" is the picture most likely to remind moviegoers of "Secretary," the 2002 sadomasochism-themed drama that put Gyllenhaal on the map as an actress willing to take big risks onscreen. Hugh Hart speaks with Gyllenhaal.
