Moore made her film debut in a bit as a nurse in the 1957 Jack Lemmon comedy "Operation Mad Ball". Her first speaking part came in 1961's "X-15". Mary Tyler Moore has the biggest role, which means she gets about twenty seconds' more time on screen than her friends. Following her success on "The Dick Van Dyke Show", she appeared in a string of films in the late 1960s (after signing an exclusive contract with Universal Pictures), including 1967's hit "Thoroughly Modern Millie", as a would-be actress in 1920s New York who is taken under the wing of Julie Andrews' title character, and the 1968 films "What's So Bad About Feeling Good?" with George Peppard, and "Don't Just Stand There!" with Robert Wagner. In 1969, she starred opposite Elvis Presley as a nun in "Change of Habit". Moore's future television castmate Ed Asner also appeared in that film as a police officer.
