So recently I have gone back to watching older and/or obscure movies. These include titles such as Bitch Slap, The Thing (1982), Lesbian Vampire Killers, Robocop, Re-animator and up next I have Black Dynamite. My taste for movies when alone typically go for older horror/monster films (I have a soft spot for non-CG gore) and Sci-Fi as well as anything that just sounds absolutely insane.
 
I now have started to compile a list of movies I plan on watching at some point, trying to keep with a certain theme, The Thing was the first.
1. Tron 1982
2. Total Recall 1990
3. A Clockwork Orange 1971
4. Back to the Future 1985
5. Gattaca 1997
6. Videodrome 1983
7. Twelve Monkeys 1995
 
Really I'm kind of all over the place, and I'm definitely not excluding movies I have not seen for years, Back to the Future being the big one here. 
 
I'm looking for more to add to this list, so let me hear some of your suggestions giantbomb! My only request is unless it is something absolutely absurd and not too well known, such as Bitch Slap or Lesbian Vampire Killers, nothing too recent.
 
Note, in the time it takes me to watch 2 more off of this list, I'll probably have watched The Fifth Element again. I own it and it's one of my favorite sci-fi movies, well movies in general. 
 
Edit: Note 2, Feel free to recommend your favorite Jackie Chan movie as well, I had started to go back through his career earlier last year.
 
Cheers
