Joseph Schenck (chairman of UA) formed a separate partnership with Pickford and Chaplin to buy and build theaters under the United Artists name. They began international operations, first in Canada, and then in Mexico. By the end of the 1930s, United Artists was represented in several countries. The remnants of that theatre circuit merged with Regal in the early 2000’s. Though not necessarily owned by UA Distribution, the theatres were the home for their movies from the 30’s to the early 50’s.Thanks, I was unaware of this information. But I read that United Artists had no theaters. UA was one of the so-called "Little Three" along with Universal and Columbia. If I am not mistaken, only the "Big Five" had theaters: 20th Century Fox, Paramount, MGM, Warner Bros and RKO.
Therefore, it is quite possible that a short film distributed by UA was screened in an MGM theater. But a short film distributed by Warner could be screened in a theater where films distributed by another of the "Big Five" were being shown? I mean before 1948. In that year the Hollywood studio system was dismantled, a federal antitrust suit forced the studios to divest themselves of their theatre chains. Among those "Big Five" there was fierce competition and maybe they would not screen their competitors' films in their theaters.
Any examples of a short film distributed by one "Big Five" preceding the screening of a feature film from another "Big Five" prior
