Which silent animated series was drawn and produced by Max Fleischer and shown before feature films?

The correct answer, "Out of the Inkwell," is a significant silent animated series produced by Max Fleischer, known for its innovative techniques and engaging storytelling. This series introduced the character Koko the Clown and is notable for its use of live-action mixed with animation, a technique that showcased the potential of animated film during the silent era.

The series is particularly important as it was designed to be shown before feature films in theaters, serving as a way to entertain audiences and draw them into the cinema experience. Fleischer's creativity in blending different media set a standard for future animated productions and highlighted the artistry involved in animation during a time when the medium was still burgeoning.

While "The Adventures of Koko" also features Koko the Clown and was created by Fleischer, it is not typically regarded as a standalone series released in the same capacity as "Out of the Inkwell." The other titles listed do not match the key characteristics that "Out of the Inkwell" is known for, particularly in relation to its production and exhibition context.
