After appearing together in “Charade” (1963), Cary Grant noted of his co-star, “All I want for Christmas is to make another movie with Audrey Hepburn." Although the pair never starred together in another film, Hepburn, the beloved actress already acclaimed for works like “Roman Holiday” (1953) and “Breakfast at Tiffany’s” (1961), would go on from “Charade” (1963) to appear in “Wait Until Dark” (1967), “My Fair Lady” (1964), and more before retiring from acting and focusing on humanitarian effort
