This awe-inspiring National Geographic documentary is as much a celebration of U.S. parks and wilderness as it is a record of one of the most audacious feats in the history of mountaineering.

The visuals are stunning, offering head-spinning views with the comfort of total safety.

Free Solo...is a jaw-dropper, both in what is documented and its visual impact.

The last act of this film is so tense, that it is almost hard to describe. The theatre was silent, as all of the audience held their breath, watching in awe as Honnold began his climb.
