Over its debut weekend, National Geographic and Greenwich Entertainment's documentary Free Solo earned over $300,000 on four screens, and set the new best per-screen average of the year, raking in $75,201 per location. That top spot was previously held by A24's Eighth Grade and Fox Searchlight's Isle of Dogs. Free Solo also bested 2006's An Inconvenient Truth for the best per-theater average of any documentary, ever.

The film follows climber Alex Honnold as he undertakes the first free solo rock climb of Yosemite’s El Capitan, and currently holds a 100% rating on film review aggregator Rotten Tomatoes. 2018 has been a banner year at the box office for documentaries, with standouts like RBG, Won't You Be My Neighbor, and Three Identical Strangers resonating with audiences and exceeding box office expectations.
