In October of 1963, producer Albert Zugsmith filed a $12,750,000 lawsuit, in Los Angeles, against Fay and ten others for allegedly libeling, slandering and harassing him, during the making of The Great Space Adventure (1963) in the Philippine Islands. The action names her and co-star George Nader as defendants, along with nine others described as newspaper columnists for Philippine newspapers and motion picture personnel. Among the allegations are charges that she and Nader conspired with other defendants and "maliciously" made statements resulting in various derogatory articles appearing in Manila newspapers.
