After some time recovering, Sellers returned to filming in October 1964, playing King of the Individualists alongside Ekland in "A Carol for Another Christmas", a feature-length United Nations special broadcast in the United States on the ABC channel on 28 December 1964. Sellers had been concerned that his heart attacks might have caused brain damage and that he would be unable to remember his lines, but he was reassured that his memory and abilities were unimpaired after the experience of filming. Sellers followed this with the role of the perverted Austrian psychoanalyst Doctor Fritz Fassbender in Clive Donner's "What's New Pussycat?", appearing alongside Peter O'Toole, Romy Schneider, Capucine, Paula Prentiss and Ursula Andress. The film was the first screenwriting and acting credit for Woody Allen, and featured Sellers in a love triangle. Because of Sellers's poor health, producer Charles K. Feldman insured him at a cost of $360,000 ($ in dollars).
