Sci-Fi Movie Riddle

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. :smiley:

Sometimes.
