There is a group called Sweetgrass productions that has a few movies out that I would highly recomend. There is snowboarding, alpine and telemark skiing in all of them. I have "signatures" (powder, powder, more powder filmed in japan) and hand cut (powder, big mountain lines, US and canada). This is the trailer for their new flick called solitaire filmed in south american locations like las lenas in argentina and portillo in chile. They put a real artistic twist on your aveage ski flick. Best ski movies being made right now IMO.
