The film was released in a silent version and in a Vitaphone version , with sound-on-disc recording of music and sound effects only . It was the fifth Warner Brothers feature film to have Vitaphone musical accompaniment . Just one month later , on October 6 , Warner Bros. released '' The Jazz Singer '' with music , sound effects , and spoken dialogue . Warner Bros. later reused some of the footage from '' Old San Francisco '' for the 1906 San Francisco earthquake sequence in '' The Sisters '' ( 1938 ) . This is Charles Emmett Mack 's final film appearance ; he was killed in an automobile accident six months prior to the film 's release
