Watch: Film fans spot Tom Cruise riding on top of a train

Tom Cruise has been spotted casually riding on the roof of a speeding train by fans in Norway, as the latest leg of Mission: Impossible 7 shoot wraps.

In a video posted to TikTok, Cruise grins broadly and waves to the cheering onlookers driving in a car alongside the track.

The movie's camera crew all seem well secured to the top of the old fashioned carriage – Cruise, however, not so much.

As if to accent this, the video comes complete with the automatic content warning: ‘The action in this video could result in serious injury.’

Indeed.

Director Christopher McQuarrie posted his own dramatic shot of the scene to his Instagram account, with a blurred helicopter in the background and Cruise scrapping on the roof.

He also paid tribute to the authorities in Norway for accommodating them.

“Norway’s scale and beauty have left an indelible and defining imprint on our film and reminded us that anything is possible,” he said

“On behalf of everyone working on Mission: Impossible, our sincerest thanks to The Norwegian Film Incentive, The Norwegian Railway Museum, the infinitely patient Stranda and Rauma Municipalities, our endlessly enduring Norwegian crew, along with everyone who supported our filming here.

“And, of course... The Mountain.

“Most of all, we give thanks to the warm and welcoming people of Norway. Your kindness and consideration are nothing less than an inspiration. We’ll miss you dearly and look forward to seeing you again.

“Tusen hjertelig takk.” (or 'thanks a lot').

Nice to see train museums finally getting their due.

Watch: Tom Cruise filmed performing stunts for M:I 7

It comes a few weeks after jaw-dropping footage emerged of a separate stunt, involving Cruise riding a motorbike off a cliff, before deploying a parachute and landing safely in the valley below in front of a crowd of adoring fans.

The shoot is now heading for Rome, returning to Italy months after it was forced to hang up its cables in February this year.

It was among the very first high-profile movies to abandon filming in the midst of the growing coronavirus pandemic.

M:I 7 was shooting in Venice, with the Lombardy region being the epicentre of the European outbreak of COVID-19.

The movie is currently slated for release in November, 2021.
