Nat Geo set to release climbers' historic ascent footage of El Capitan

Film to get theatrical release, followed by global broadcast on National Geographic in 171 countries

National Geographic has captured the historical solo climb of El Capitan by rock climber Alex Honnond and is soon set to release the footage.

The new docu-feature, tentatively titled "Solo", will document the 3,000-foot vertical rock journey at Yosemite National Park, with National Geographic Documentary Films, reported Deadline.

Jimmy Chin and E Chai Vasarhelyi have directed the film, which will get a theatrical release followed by a global broadcast on National Geographic channels in 171 countries.

Hannold completed the climb, which is considered the highest, most dangerous rock-climbing track ever attempted, in 3 hours 56 minutes with the cameras rolling.

"Alex's passion to push himself to the edge of what is humanly possible, to continually redefine the limits set for him, encompasses everything we represent at National Geographic. He is a true explorer in every sense of the word, one who fully embodies the pioneering spirit," said Tim Pastore, president of original programming and production at National Geographic channels.
