‘The Collective’ became Anthill Films and are still making great, feature length MTB films, although it might be 2/3 years since the last one.
I seem to recall they have been struggling to make it pay, when so much stuff is free to view now.
As for stuff like their stuff, Deathgrip is very good, great visuals without some of the slightly blithering voice-over stuff Collective / Anhill do “travelling is about destination, but in mountain biking isn’t about the destination” or so other meaningless nonsense.
As far as I can tell the British Pie thing is nothing like it, it just seems to be Lads, Lads, Lads, lots of mud and crashing to everyone else giggling. It’s filmed hand-held at the trail side by someone who bought a fisheye lens once and insists on using it at every opportunity. It’s like Roam like Street Hawk is like Easy Rider, because Motorbikes. That’s not to say it’s not good, it’s just not like Roam et al.
