Mission Impossible director Brad Bird said Tom Cruise was ‘bummed out’ when they finished filming scenes on the world’s tallest building.

Cruise, 48, is reprising his role as Ethan Hunt for the fourth installment of the movie franchise, which the Incredibles director has taken the helm of.

Some of the scenes for the new movie were filmed on top of the Burj Khalifa, the world’s tallest building, in Dubai and Bird spoke about Cruise’s stunts on top of the building.

He said to MTV News: ‘It’s big and it is crazy. I think the craziest thing is that they’re real they’re not digital. That’s Tom Cruise on the tallest building in the world, he’s doing all that stuff.

‘People won’t believe it, but we shot it in IMAX so it’s there for everyone to see.’

Bird added that Cruise was disappointed when scenes were finished on top of the building.

He said: ‘He actually lives for that stuff. He loves it. Loves it. The day we finished shooting on the Burj, everyone suddenly relaxed because nothing had happened, no one had gotten injured or died, and the only one who was bummed out was Tom because he had to come down from the building. He loves that stuff.’
