The production studio was a former church on E. 2nd St. in Manhattan (near Houston St.). It was a two-story structure, ground floor had a fully equipped kitchen and rooms for offices, the second floor had a high ceiling and a balcony running around it. This per interview with Kermit Love, stop-motion animator, published in "Closeup" magazine #2, 1976.
The stop-motion puppets were called "kinemins" by producer Michael Myerberg, who claimed they were controlled electronically. In truth, however, the only thing electronic was the electromagnetic plate that served as the floor of the sets and which kept the stop-motion figures in place.
