By skyforbes I find it funny that Sid Sheinberg while he was at MCA / Universal thought of the title Spaceman from Pluto instead of Back to the Future. The memo that Steven Spielberg sent back was just as funny that nobody heard from Sid since.
It reminded me of the same scenario where WB didn’t want a film title like Gremlins as Spielberg relied back, why not just call it “People”. Or how Beetlejuice was almost called House Ghost.
