Hello folks,
I am not surprised that you did not heard of this movie before. When I grow up in 1970s, once or twice I watched one of science-fiction movies about the time portal (much like big TV screen) allows anyone to enter through. There are no closed caption on that. I hope that someone would make DVD subtitle for that.
Also, I checked it on Wikipedia and noticed that "Journery to the Center of Time". When I read its description, I now remember that I watched it about sphere-shaped time ship once or twice but still no closed caption/subtitile too.
I can't believe that I never forget many time-travel movies that I watched 30 years ago once!
