"Cascadia" was filmed exclusively with GoPro action cameras. But what if a camera breaks, does Danny MacAskill have to repeat all the incredible tricks again? A look over the shoulder of the film crew.

The latest video clip from Danny Macaskill in Cascadia was the video highlight of 2015. The "behind the scene" clip sheds light on the difficulty of the shoot and, above all, the tricks.

He's been on the big stages for some time now. Danny MacAskill with his "Drop and Roll - Tour". Now he shows how much rock n roll there really is in his crew and none other than rock legend Rob Halford from Judas Priest adds his two cents. Although the clip doesn't come close to its predecessors in terms of action, it is also more of a wink and a promo clip for his "Drop and Roll - Tour".
