In a world dominated by superhero franchise juggernauts and book adaptations and reboot after reboot after reboot after reboot, original concepts for science fiction movies are few and far between. Which is weird, because these movies tend to be extremely good (here’s looking at you, Oblivion, Looper, Moon, etc.) but they also tend not to do as well as they should at the box office, probably because they don’t have recognizable costumed heroes and formulaic plots that we can bundle ourselves in like giant, loud security blankets. Thankfully, probably due to its sheer star power and the fact that it did better than most, 2014’s Edge of Tomorrow is getting a well-deserved sequel, and according to its director, it’s poised to change the world of sequels forever.

Director Doug Liman, speaking to IGN about his plans for Justice League Dark, had a pretty bold statement about Edge of Tomorrow 2. When asked if it was still on track, he said:

Yeah, it’s going to revolutionize how people make sequels. It really will.

Wow. Okay. He demurred when asked for some more explanation, and simply said that he couldn’t say exactly why or what it was about, but that we should “mark [his] words.”

Later, in an interview with Collider, he let slip a few more clues as to how he was planning out the sequel. Apparently, it’s not a sequel at all — well, actually, it is a sequel, but it’s also a prequel.

That is the only sequel that I’m considering doing, and it’s because first of all the story is so amazing—much better than the original film, and I loved and loved the original film—and second of all, it’s a sequel that’s a prequel.

It’s not as weird a statement as it seems. A big part of Edge of Tomorrow was time travel: its protagonist was a soldier fighting un-fightable alien monsters, who ended up stuck in a time loop that took him back to a certain point every time he died, to repeat his actions all over again. It wouldn’t be a stretch to assume that Liman is playing around with the same ideas for the sequel-prequel (sprequel?), perhaps taking us forward in time in order to take us back.

Edge of Tomorrow 2 doesn’t currently have a release date.
