"Sometimes it was tough doing take after take upside down! I did a lot of that sort of thing"

John Astin's quote talks to the dedication and hard work that goes into making a movie. It is likely that he was describing a scene in which he needed to carry out upside down, and had to do multiple takes of the exact same scene. This could have been a physically requiring task, as he would have needed to maintain the exact same position for an extended period of time. It is a testament to his dedication to his craft that he was willing to put in the effort to make certain the scene was perfect. His quote also speaks with the dedication of the whole cast and team, as they all worked together to make certain the scene was best. It is this sort of commitment that makes a film fantastic, and it is clear that John Astin was a part of that.
