Krazy Kat and Ignatz Mouse at the Circus

The film 'Krazy Kat and Ignatz Mouse at the Circus' was released in 1916 as part of the silent Krazy Kat series produced by William Randolph Hearst's International Film Service. Under current US copyright law, all works published or registered before January 1, 1928, have entered the public domain regardless of renewal status. As a US production from 1916, the maximum possible copyright term expired no later than 75 years after publication (under the 1976 Act) or was already public domain before the 1998 Term Extension Act (Sonny Bono Act) took effect. Because the copyright for any work from 1916 has elapsed the 95-year statutory limit, the film is definitively in the public domain in the United States.
