The "Mission: Impossible" movies are redefining what "impossible" really means.

Director Christopher McQuarrie is talking a big game about "Mission: Impossible 7" and its follow-up, which he is shooting back-to-back. The next new movies are going to be huge, he says — really huge.

"I pitched the idea of making two movies, and now I have to justify why it’s two movies,” he told Empire. “You’ve got to earn that. You’ve got to make something that swallows the last three movies whole.

McQuarrie, who directed "Fallout" and "Rogue Nation," added, "I’m freaked out now. We’ve talked ourselves into something. Holy shit.”

The "Mission: Impossible" movies have been attempting to top each previous one with eye-popping setpieces featuring star Tom Cruise (who is notorious for doing his own stunts, even if it means injuring himself in the process).

"Fallout" featured a high-speed motorcycle chase, a foot race across rooftops (in which Cruise broke his ankle), a HALO skydiving jump, and an insane helicopter chase/crash.

What could Cruise possibly do next? Even McQuarrie isn't sure.

"Here’s the problem with going to the moon: How do you fall from the moon?” he pondered.

"Mission: Impossible 7' and '8' are slated for release in summer 2021 and 2022.
