The British film "The Man Who Never Was" (1956) featured Webb playing the part of Royal Navy Lt. Cmdr. Ewen Montagu in the true story of Operation Mincemeat, the elaborate plan to deceive the Axis powers about the Allied invasion of Sicily during World War II. In "Boy on a Dolphin" (1957), second-billed to Alan Ladd, with third-billed Sophia Loren, he portrayed a wealthy sophisticate who enjoyed collecting illegally obtained Greek antiquities. In a nod to his own identity, the character's name was Victor Parmalee.
