Though the upcoming sure-to-be-blockbuster film Inception will not be in 3-D, director Christopher Nolan has admitted trying “3-D tests,” and intimated that a 3-D Batman could be tough to avoid, according to the Los Angeles Times. As the idea of an exclusively three-dimensional future sinks in, let’s flirt with sacrilege a bit and consider which classic films could have been one dimension more awesome.

Terminator 2: Judgment Day: Perhaps Avatar czar James Cameron should have waited a couple years in order to bring this blockbuster into 3-D fruition. Using the layered planes effect from Avatar, the motorcycle chase scene could be even more exhilarating. (I’m focusing especially on the shot at 3:09 of this clip.)

Being John Malkovich: Who says only action movies benefit from extra dimensions? In addition to augmenting the claustrophobia that is the seven-and-a-half floor, 3-D technology could enhance the portal into Malkovich’s brain, allowing the viewer to really see the world through his eyes.

Die Hard: In the movie that set the standard for modern action films, the famous “elevator scene” set the standard for Bruce Willis blowing stuff up. I’d love to see the flames ripping up the shaft in 3-D. Maybe they could even turn up the heat in the theater for some sensory overload. (Start clip at 1:12)

Spider-Man: If there is anything to learn from Avatar and How to Train Your Dragon, it’s this: Flying sequences in 3-D > actually flying. What could be better than gliding around the Big Apple with Spidey via the already impressive web-slinging sequences?

PopWatchers, what do you think? Which classic movie do you think could have benefited from today’s 3-D technology? Who’ll be the first poor soul to suggest Citizen Kane: 3-D?
