Tobis Film was a German film production and film distribution company. Founded in the late 1920s as a merger of several companies involved in the switch from silent to sound films, the organisation emerged as a leading German sound studio. Tobis used the Tri-Ergon sound-on-film system under the Tobis-Klang trade name. The UFA production company had separate rights to the Tobis system, which it used under the trade name of Ufa-Klang. Some Tobis films were released in Germany by the subsidiary Europa Film.
