The Die Hard series is quite fantastic, it has to be said.
But it doesn't have anything on The Fifth Element. That wins by virtue of Milla* alone, nevermind that everything else is completely awesome (Zorg!) and it's one of the best movies I've ever seen.
* Bunny, you're an alien. Even straight girls and gay guys are hot for her. The only possible explanation for being the only person on the planet who doesn't find her gorgeous is if you're not FROM this planet.
