A friend posed this riddle to me, and I can’t find it for all the Google-fu in the world!
Ok, here it is:
One-Word Title of a sci-fi novel-turned movie (from the 80’s). If the letters of this one-word title are all shifted one letter, alphabetically, you get the name of another movie based on a novel.
The shift is like NEAR=PIES. The Vowels are shifted separately.
Hope this is easy to understand.
Can you figure this out?
1984 = 2010.
Yeah, I know it’s not right, but you’ve got to start somewhere.
How about
Tron = The Adventures of Buckaroo Banzai Across the 8th Dimension
Also, is it an American film, or at least English Language?
I tried TRON first and got nothing.
I tried
DUNE, first forwards, then backwards and got COMA. It wasn’t in the 80’s, but the question as worded doesn’t say the second film needs to be.
I think Uncle Martin got it.
Wow. Uncle Martin knocked that one right out of the park! I love the dope.
Great job, UM
Aw, shucks.
I really just lucked out picking the right one to start with. It probably helped that the example was 4 letters.
Heh, doesn’t surprise me Uncle Martin’s right. That was the first film that popped in my head upon reading the OP as well.
PS. Was Tron based on a novel? Or did people just forget that part?
TRON was loosely based on Hardy’s “Jude the Obscure.”
I first thought of DUNE also and was about to google the obscure czech sci-fi film EYPI, which surely exists. Right?
What did you expect from a Martian ?
Very loosely. 
Sometimes.
