Kevin Costner is in talks to play the male equivalent of Mrs. Robinson in the Warner Bros. comedy that advances the storyline of ’60s pic “The Graduate.”

Jennifer Aniston is already set to play the young woman seduced by Costner’s character. Shirley MacLaine will play her grandmother, the woman who inspired the character immortalized by Anne Bancroft.

Ted Griffin wrote and will direct the as-yet-untitled pic. Section 8’s Steven Soderbergh and George Clooney are producing with Paula Weinstein. Shooting starts in the summer. Griffin, who scripted “Ocean’s Eleven,” is making his directorial debut; Jennifer Fox and Ben Cosgrove exec produce.

Story concerns a young woman who puts her marriage plans on the shelf so she can return home to Pasadena and unravel family secrets. She has discovered that “The Graduate” was probably based on her family, her grandmother was Mrs. Robinson and she doesn’t know her real father.

Last seen in “Open Range,” Costner most recently shot Mike Binder’s “The Upside of Anger.” MacLaine wrapped the Curtis Hanson-directed “In Her Shoes” and is preparing to play Endora in Nora Ephron’s “Bewitched.”
