Kathleen Turner is on a massive, high-profile hunt in London to find the right young man to debauch. The search is strictly professional, however. The actress is set to play Mrs. Robinson in a British stage adaptation of the Charles Webb novel “The Graduate,” which, you may remember, was turned into a seminal 1967 youth film that starred Dustin Hoffman as the guileless grad Benjamin Braddock and Anne Bancroft as the predatory seductress Mrs. Robinson. Terry Johnson wrote and will direct the play.
