In 1926 Warner Brothers's premièred "Don Juan", a film with music and sound effects, and the following year released "The Jazz Singer" with dialogue and singing scenes. Along with other big companies, Paramount initially resisted adopting sound films and continued to exclusively make silent ones. Wanger convinced his colleagues of the importance of sound, and personally oversaw the conversion of 1928 silent baseball film "Warming Up" to sound. The sound version had synchronized music and sound effects without dialogue. After the film's successful release, the company switched dramatically away from silent to sound.
