Hmmm. Good topic! Influenced and effects on MTU...As we haven't specified, I will include TV*, and Anime DVDs** as well.
perhaps if I broke it down by what, when where and how?
For Corporate aspects Good and Bad:
the 'Aliens' series of movies;
Outland [of course];

Paycheck [corporate espionage];
Johnny Mnemonic[corporate espionage];
5th Element[corporate greed & Security troops];
Babylon 5*;
Firefly*;
Cowboy Bebop**;
Outlaw Star**;
Ghost in the Shell**;

and Blade Runner.
For scenes in High Populated worlds [crowded arcologies-mega cities]:
Blade Runner;
Johnny Mnemonic;
Cowboy Bebop**;
Outlaw Star**;
Ghost in the shell**;
Star Wars episodes 1-3 [Coruscant in particular];

A host of vintage war films from medieval to Desert storm era.. just to cover TL-2 thru 8!
For the Aliens in SF:
Babylon-5*;
Star Wars 1-6 [I find can live without the Ewoks though];
Star Trek*, ST NG*, ST Voyager*;Deep Space 9*; [although MTU doesn't have dna compatibility like Rodenberry's with every species out there];
Aliens;
and Predator.

Firefly*;
Cowboy Bebop**;
Outlaw Star**;
Titan AE**;
Star Wars 4-5, the Millenium Falcon;
Red Planet;
and Event Horizon.
Action-crime-drama films I peruse for Rogues and law-breaking stuff, too numerous to mention, but the criminal & legal/Law enforcement aspects of the above listed films and series also fall into this category and thus do not bear repeating.
