Let’s talk about alternate dimensions.

“How did we get this far?” asks Reg E. Cathey as Dr. Franklin Storm in the the 2015 “Fantastic Four” trailer’s introspective voiceover. “Human beings have an immeasurable desire to discover. To invent. To build.”

But if the last few years of superhero movies are any indication, the studios are less interested in creating new content than they are remaking proven franchises.

In “The Amazing Spider Man” in 2012, we got a brand-new webslinger, just five years after Tobey Maguire’s incarnation.

In April, we’ll be re-introduced to a made-for-Netflix version of the Daredevil.

2013’s “Man of Steel” came just seven years after “Superman Returns” faded from the screen, and don’t even get me started on the number of Batman movies that have been made – with yet another Caped Crusader set up for 2016.

Notably, the entire X-Men franchise just used a time-travel storyline to retcon the last several movies, thus pushing virtually all offerings from more than five years ago into an alternate universe storyline.

By this logic, the “Fantastic Four” franchise, the 2000’s run which is generally considered unimpressive, was due for an update.

From the beginning, the movie seemed controversial. The actors and actresses selected to play the titular super-squad all fall squarely in the 20-something age range, at least in terms of the characters they play onscreen.

One of them is African American, which – gasp! – contradicted some diehard fans’ idea of what “sticking to the comics” entailed.

But the most important change, made glaringly obvious in this trailer, is the use of the “Ultimate” Fantastic Four comics to base the plot, according to Marvel Wiki.

In contrast to the earlier movies, which posited that a trip to space gone wrong caused four members of a scientific team to gain body-altering superpowers, the “Ultimate” comics have an extremely young Reed Richards (here played by Miles Teller in Buddy Holly glasses) discovering an alternate universe called the N-Zone.

It’s another experiment-gone-bad that causes five people (the Fantastic Four and Dr. Doom, natch) to change into superhumans who are then restrained by the military and periodically attacked by a vengeful Doom.

There’s also a mole person at some point, apparently, but I’m not sure that’ll come up.

It’s a premise that could go so wrong, but in the hands of “Chronicle” director Josh Trank, could also be fascinating.

The potential for body horror is actually pretty high when you consider that all of the team’s members’ bodies are warped in some way by their new abilities, and the fear of the public toward the unknown tends to be used to pretty good effect in movies.

It’s these elements that I hope will ground the potentially-kitschy alternate dimension storyline – something with an obvious potential for cool visuals, but that could crumble if overexposed to science jargon or forced suspension of disbelief.

It’s a bold move to dramatically change a franchise’s origin story, but it may be the best way for this superhero movie to move forward.
