There’s two types of MTB movie for me: those that amaze and those that inspire. I’ll never tire of seeing Mackaskill perform that front flip to flat off that bothy in Skye, nor of the big air movies; the kind of stuff that astounds me. As a couple of people said above, Vast is a good one to inspire since it combines the feel of a big movie with top riders, but in settings that are mostly realistic targets for the average rider. Ditto for Dirt.
I think Chris Askrigg manages to amaze and inspire better than anyone. There’s no way I’ll ever have 1% of his talent, but he makes me want to get on my bike more than anyone. A Hill in Spain is brilliant
My absolute very favourite at the moment is Danny Hart’s World Champs winning run from Champery though. It sends shivers through me
