I think there is two major factors there.
First of all, to make good videos there is the need for some equipment, and you need to be ready to accept that a camera to 1000 quid gets ruined.
Also it takes very much time, ive been making videos for 3 years now and some of the first videos i made was nothing special, but by time the editing skills and my contact with car owners has improved so i get to mount my equipment in such awesome cars as the wrc escort and that black supra.
We are also very lucky here in norway as the track day regulations are very keen, as they allow very "track damaging" driving, as spinning around on the gras or stopping on a straight to take a burnout.
As far as i know in england for instanse doing that would permanently ban you from that track.

The other fact is that norway is such a small country with few racing circuits, this means that all the badass cars is gathered when there are meets, this again means that the all get featured in the same films, this way you can make films with one awesome car after another.
sweden has also understanded that to have track days that are friendly for the audience they need to loosen the restrictions so more insane driving can be done, so expect some wild movies from there too.

Hope you who ordered the movie will be satisfied, unfortunatly i had to work a bit late on friday, so the dvd's didnt get shipped until saturday, so expect them to be in your postbox by tuesday/wednesday i guess.
