Forbidden planet was an awesome movie for itcs day and fairly serious science fiction. It acknowledged that "rocketship" would not be useful for interstellar travel and had "hyper drive", which was apparently a rough ride to enter or leave.
Robby was an intelligent design, not just a walking boiler. The parts in his made sense. He had a gyroscope to maintain balance, vertical and horizontal scanners to see with, crystal plates to recorve sound vibrations to hear with, relays to access memory and logic circuits to think with, etc.
The movie was based on shakespeare's play "the tempest" with morbius playing prospero.
I thought I was a very courageous movie to make at the time. The line "Morbius, we're all part monsters in our subconscious, so we have laws and religion! "
I mean wow! That was a ballsy line for the 50's. It essentially implied religion may be a human invited nation to deal with our all too real inner deamons from our Id, and not the literal truth. In the 50's when you he anti commie hysteria, the McCarthy hearings, etc, making a statement like that took real guts
Everything abut this movie was truly wonderful. The krell machine, tho simple animation, gave a sense of awesome scale that I didn't see again until star trek the motion picture.
This definitely deserves the title of one of the world's best movies.
BTW ER, if you like intelligent SF movies I have a few recommendations .
Quatermass and the pit. Known in america as 5 million years to earth, this was an intelligent SF horror movie I can't recommend enough.
Ikarie XB1 is an eastern European 60's SF movie that has at times been compared to 2001.itcs not an action movie but deal with an interstellar journey at subkght speeds. How do people survive it, keep sane, live for years on a ship knowing their familes are aging back on earth due to time dilation, etc.
Planet Bur. Another eastern bloc SF movie. Somewhat intelligent actually.
Little heavy on the soviet propaganda tho. Might not be your thing.
