Found this on another forum and figured I'd post here. As we all know, movies tend to get remade quite a bit, and sometimes with a setting update to contemporary times of the new film's release. So thought I'd ask guys what are some movies that can't be remade in your opinion, or at least if they were, can't be updated to modern times. Will list a few I think will apply as well:

Jurassic Park
Jaws
The Exorcist
Ace Ventura

Just to name a few. Thoughts?

We don't need those live action Disney remakes
