The production arm of the studio still struggled. While there were to be a few hits like The Killers (1946) and The Naked City (1948), Universal-International's new theatrical films often met with disappointing response at the box office. By the late 1940s, Goetz was out, and the studio returned to low-budget films. The inexpensive Francis (1950), the first film of a series about a talking mule and Ma and Pa Kettle (1949), part of a series, became mainstays of the company. Once again, the films of Abbott and Costello, including Abbott and Costello Meet Frankenstein (1948), were among the studio's top-grossing productions. But at this point Rank lost interest and sold his shares to the investor <answer>Milton Rackmil</answer>, whose Decca Records would take full control of Universal in 1952. Besides Abbott and Costello, the studio retained the Walter Lantz cartoon studio, whose product was released with Universal-International's films.
