This film made its way to the U.S. theaters a few years after its release. I must have seen it when I was 7 to 9 years old in Maine sometime between 1960 to 1962. It made such an impression on me that I think of some of the black and white images to this day. I agree with others thinking that the title should have been The Magic Marble. The most memorable use of the marble was to stop time, which impressed me the most. So much so that I don't recall the runaway steamroller at all. My young mind must have stopped watching the movie and focused on what I would do if I could stop time. If it was in distribution I would consider buying a copy just to relive that memory.
