I'll stick with THE DAY THE EARTH STOOD STILL, although that was agitprop too. Whaddaya gonna do?
I hope you are talking about the original TDTESS.
The only problem with the Film was that the Aliens could shut down Electrical Generation worldwide, making exceptions for Planes in flight, Hospitals etc., but they threaten to destroy the entire Planet if we weaponize Space.
Well, without Electricity, there ain’t no Rockets going anywhere. The Human Race would just be in a perpetual early 1800’s state for eternity.
One of my favorite trivia items about the Film was the question of the Robot Gort. When they asked the designer how he came up with a Costume that had no visible openings for the Actor to get into it, he had a very simple answer.
There were TWO Suits, one with a zipper in the front and the other with a zipper in the back.
Hope you mean the 1951 TDTESS with Michael Rennie instead of Kenau Reeves. :) Much better.
