Ask any mega fan of Arnold Schwarzenegger what his three best ‘80s films are, and I guarantee you'll get the following three movies: Conan the Barbarian, Predator, and The Terminator.
Sure, somebody might swap Conan for Commando (the best action movie ever), or The Running Man (and I wouldn't fault them for it since it's definitely one of the best sci-fi movies of the ‘80s), but Predator and The Terminator are certified locks, and I dare you to find somebody who says otherwise.
