I just watched this historical movie about trains. Probably it is one of the first movie of it’s kind. Nowadays we call it a short movie (and boring,not if we see it from a different point of view) but by that time a 15-20 minutes movie it was something great. I think that this project to make the movie and all the toys, and also trying to give them a realistic character it took a long time and resources. Back in 1970s, the resources were more limited which it make it harder and more expensive, that’s why I’m saying it was a fantastic movie.
