In 1920, Slavko Vorkapić, an artist from Vojvodina (now Serbia) emigrated to the United States. He roamed the country for a year and ended up in Hollywood where he became a master of special effects. He began to teach at USC where a young student, Art Clokey was starting his film studies. Art Clokey also happened to tutor the son of Sam Engel-- famous producer and President of the MPAA. Clokey, mentored by the special effects master at USC, made a little art film using stop motion and claymation. One day he showed his "artsy" student film to Engel. When it was over, Mr. Engel said: "Art, that's the most excting film I've ever seen. We've got to go into business together." That is the story of Gumbasia (video). And the rest is history (previously on MeFi).
