Tom Cruise delighted fans again this week with an exclusive peek behind the scenes of Mission: Impossible – The Final Reckoning.

Posting to Instagram, the 63-year-old Hollywood superstar unveiled footage of himself suiting up in a wetsuit and plunging into a deep-water tank – training that involved enduring extreme oxygen deprivation.

“I trained for over a year to be able to physically handle the amount of oxygen deprivation,” Cruise explains in the clip’s voiceover.

Director Christopher McQuarrie also appears in the video, saying, “I’m always surprised by what it is we’re doing.

That’s the amazing thing about this franchise — it’s all about constantly pushing the envelope as far as we can.”

In his caption, Cruise extended heartfelt thanks to his team, saying,“Thank you McQ and our entire cast and crew for this experience of a lifetime.

I hope everyone enjoys all of the extras and that it gives some greater insight into what it takes to make a Mission: Impossible film.”

Other B‑roll highlights include him dangling dramatically from a plane mid‑stunt and gripping the wheel of a car as it flips through a tunnel.

Following his daring film featurette, the acting legend made headlines last month as he was spotted in the crowd amid 90,000 Oasis fans at Wembley Stadium.

Oasis’s reunion tour, dubbed Live ’25, marks their first time on stage together since 2009.

In addition to London, the band is set to play Edinburgh, Dublin, and venues across North America, Asia, Australia, and South America.

He was also said to have been at the event with longtime collaborator and romance‑rumour partner Ana de Armas.

Other stars included Dua Lipa and fiancé Callum Turner were snapped singing “Don’t Look Back in Anger” with Noel’s daughter, Anaïs Gallagher, while Fearne Cotton called the night “magic,” praising Liam’s brash stage presence and Noel’s “gorgeous atmosphere.”

Mission: Impossible – The Final Reckoning was released in cinemas in May and was also released on digital download on Tuesday.

It comes as Cruise gives his final portrayal of Ethan Hunt, alongside an ensemble cast including Hayley Atwell, Ving Rhames, Simon Pegg, Esai Morales, Pom Klementieff, Henry Czerny, and Angela Bassett.

While fans online suggested the star could be back for another film, Tom has debunked the rumors as he spoke out at Cannes Film Festival, saying, “It’s the final,” and added, “It’s not called final for nothing.”
