Sorry, but you can’t leave The Day The Earth Stood Still out of the mix, even if it was a few years earlier (1951).
I thought TDTESS was really boring. Could never sit through the whole thing.
*********************************
I like the original movie version of TDTESS, and have read Farewell to the Master. But, for the movie, they actually ripped off another story.
Just think:
A Superior Being descends from the sky, and tries to get out among the people to tell them they are screwing things up, and if they don’t stop, bad things are going to happen to them. The Superior Being is accompanied by an Unearthly Force, which rules over the Superior Being, and all other beings.
The authorities are so disturbed by what the Superior Being is saying that they have him killed.
But the Superior Being is brought back to life temporarily, by the Unearthly Force, and warns the people one last time to mend their ways, or they will be punished by the Unearthly Force. Then the Superior Being ascends back into the sky.
Where have we heard this story before?
