Actress Emma Stone worked overtime for the Gilda Radner Benefit luncheon at the Essex House Wednesday. She provided two tickets to “SNL” and two tickets to “The Amazing Spider-Man” premiere in LA on June 28 for the raffle, and amused the crowd with a spot-on impression of Radner’s Roseanne Roseannadanna “SNL” character.

Stone, a Gilda’s Club NYC ambassador, added that her mother, Krista, a breast cancer survivor, introduced her to the comic talent of Radner, who died of ovarian cancer in 1989.
