Frankfurt, Germany, 1959: Actor Jack Lemmon (top) and screenwriter I.A.L. Diamond walk up the steps to board the plane at Rhein-Main airport. They — together with director Billy Wilder — stopped over briefly at the Frankfurt airport en route from Berlin to Zurich, Switzerland, on a tour promoting their new movie “Some Like It Hot,” in which Lemmon co-stars with Marilyn Monroe and Tony Curtis. Lemmon’s next movie is titled “The Wackiest Ship in the Army” and will feature the 34-year-old actor — who was an ensign in the Navy — in the role of a lieutenant in command of a sailing ship on a secret wartime mission. “This new film ... is based on an actual story,” the actor told the assembled journalists on the tarmac. “It seems the Army once did have two ships assigned to it, during World War II, and the picture is about one of them.”
