Universal City Zoo
United States
Universal City Zoo was a private animal collection in southern California that provided animals for silent-era Universal Pictures adventure films, circus pictures, and animal comedies, and to "serve as a point of interest" for tourists visiting Universal City. The animals were also leased to other studios. The zoo was closed in 1930, after cinema's transition to synchronized sound complicated the existing systems for using trained animals onscreen.
