Vitaphone at the Tower
This July 1928 ad that Ken McIntyre found advertises "The Lion and the Mouse" as the "First Vitaphone Talking Picture" -- presumably "all-talking" as opposed to just a few scenes as in "The Jazz Singer." The feature was based on a New York stage success. The Tower had earlier had a moveover run of "The Jazz Singer" after its first run engagement at the Criterion.
