Tom Cruise's Ultimate Stunt: Breathing in Carbon Dioxide for Mission: Impossible 8
Few actors in Hollywood commit to their roles as fiercely as Tom Cruise. Over the years, he has hung off the side of a plane, scaled the Burj Khalifa, and performed high-speed motorcycle chases—without a stunt double. Now, for Mission: Impossible – The Final Reckoning, he's gone even further, filming an underwater scene that had him breathing in his own carbon dioxide.
A Deep Dive Into Danger
Speaking to Empire Magazine, Cruise and director Christopher McQuarrie unveiled the extreme lengths taken to shoot this ambitious sequence. The scene involves Ethan Hunt diving into the wreckage of the Sevastopol submarine, following the cliffhanger ending of Mission: Impossible – Dead Reckoning Part One. Filmed in an 8.5-million-liter water tank, Cruise wore a specialized suit and mask that allowed only 10 minutes of use before oxygen deprivation set in.
“It builds up in the body and affects the muscles,” Cruise explained. “You have to overcome all of that while you're doing it, and be present.”
McQuarrie added that the challenge was not only to keep Cruise safe but also to translate the chaos and physical toll onto the screen. “He's in a rotating structure filled with debris. We had to make it look as disorienting as possible while keeping it repeatable and survivable.”

The Art of Controlled Chaos
Cruise's unwavering commitment to realism continues to redefine action filmmaking. His philosophy? Practical effects over CGI. Every stunt carries real stakes, amplifying tension for audiences. Whether it's HALO jumping from 25,000 feet or hanging onto a speeding train, Cruise believes in immersing the audience in genuine peril.
For Mission: Impossible 8, the intensity is turned up yet again. With McQuarrie at the helm, and a stellar cast including Hayley Atwell, Simon Pegg, Vanessa Kirby, and Ving Rhames, the franchise aims to deliver another breathtaking installment. The official synopsis keeps it mysterious: “Our lives are the sum of our choices. Tom Cruise is Ethan Hunt in Mission: Impossible – The Final Reckoning.”*
Personal Impressions: Pushing the Boundaries of Cinema
If there's one thing you can count on, it's Tom Cruise's relentless pursuit of perfection. At a time when blockbuster films rely heavily on CGI, Cruise reminds us why practical stunts still matter. Watching him push himself to the brink of physical endurance isn't just thrilling—it's inspiring.
However, as much as I admire Cruise's dedication, I also wonder: at what point does commitment cross the line into recklessness? He's 62 when Mission: Impossible 8 hits theaters. Can he sustain this level of intensity, or is he setting an impossible standard for future action stars?
That said, this isn't just about one actor's daring stunts. It's about the legacy of Mission: Impossible. The franchise has consistently redefined modern action filmmaking, proving that practical effects and smart storytelling still reign supreme in an era of excessive digital wizardry.
