Without Meyer, No Celebration is Complete (German: Keine Feier ohne Meyer) is a 1931 German comedy film directed by Carl Boese and starring Sig Arno, Ralph Arthur Roberts and Dina Gralla. Boese made a number of films featuring Jewish comedians during the Weimar Era. Using only the above description and what you know about the world, "Carl Boese had a Jewish comedian appear in a film before the Weimar Era." is definitely correct, incorrect, or inconclusive?
