I saw this movie in Cedar Rapids, IA in about 1969. It had a lasting impact remembering it since I was three. Since posting I have found that the Xerox company made it and you can find it at some libraries in the USA ---- ----Spoiler Warning ------- what I remember about TWM is two kids that are friends climb into a tall rocket type capsule that is the wishing machine. They have great voyages and fantastic adventures and leave it to a normal life only to return back to it for more adventures later. Perfect for kids about my age at the time (threefour). Check it out if you find it, I think it is a masterpiece and very relevant to the cold war.
