How on earth do they do that?
Over and over again I could have used the same phrase to describe the eye-popping stunts of the world's greatest extreme sportsmen and women.
At The Very Last Moment is the latest in a ten-year series called Nuit De La Glisse. It is in 3D but I have to confess, I saw it in 2D, thanks to an internet link-up.
However, this did not stop be being awestruck at the incredible feats of surfers, skiers, kayakers, extreme cyclists and people flying through the air on what seemed to be jetpacks.
At one point one skier seems to defy gravity as he negotiates a virtually sheer face, causing a huge shift of snow in the process.
Another goes 300ft of the edge of a cliff!
The film splits into two parts - one recalls the most amazing incidents recorded in the series over the last decade.
The new stuff followers extreme sports stars to Greenland when, in the most inhospitable surroundings, they perform the most astonishing stunts.
Anyone interested in extreme sports will be utterly fascinated by Thierry Donard's film.
I have to say, after my initial amazement, I felt it lacked three features which would have made it so much better.
Firstly, I wanted to know more about the participants. TT3D engaged me so much last year because I got to know Guy Martin and co before I saw them risk their necks.
Secondly, I needed to see failure. Rarely in this movie do the athletes do anything but succeed to the point that they made it look too easy.
Great sports movies show glory in the face of adversity.
And, most importantly, there needed to be a far more engaging narrator. This one sounded like she was describing a Thai temple rather than someone taking their life into their hands.
So, plusses and minuses.
No laughs, no jumps (at least from me), no vomit or nudity.
Its overall rating, because it lacked these elements, was 6/10.
