Climbing documentarians Peter Mortimer and Nick Rosen are known for films such as "The Alpinist" and "Valley Uprising." Now the directors are out with a four-part documentary series "The Dark Wizard," which premieres on HBO Max on April 14.

The documentary traces the life of Dean Potter, who was well known in the world of climbing for his bold free soloing, BASE jumping, and highlining. But the human behind those efforts was quite complicated, something that is illustrated through interviews with friends, family, and climbing partners—and archival interviews with Potter himself.

Mortimer and Rosen reflect on their own relationships with Potter, whom they filmed with often before he died in a BASE jumping accident in Yosemite in 2015. The pair share why they felt this film needed to be made in an honest way and how Potter's journals, provided by his sister, presented a lesser-known side of him, one that was quite vulnerable.
