Fantastic Planet is not necessarily about mind control or brain washing it does however tell a very unique tale on how the human race came to be so evolved and I find the ancient pyramids and monuments that are so large and that we're still very baffled to how they were created using sticks and stones basically to be very interesting. I've always had the notion... what if they were built to scale for their time. What if back in those times Giants or beings much much larger than we are now ruled the planet back then and built these statues and pyramids to a size proportional to them... after all in all these monuments and even cave drawings from 1000's of years ago they show really tall people standing next to small people. That tells me we have a lot to learn about our planets history as well as the our species history!
If you know of any other movies about mind control, brain washing, project MKULTRA or some fictionalize conspiracy you find treads the line between fact and fiction please mention it!
