The Dark Divide

Pyle, a lepidopterist, sets out on a 30-day trek through the Gifford Pinchot National Forest to document butterflies and moths following the traumatic death of his wife from cancer. An inexperienced hiker, Pyle encounters challenges including frightening wildlife and getting lost in a cave. When he completes the hike, taking far more days than he had expected to, he leaves the wilderness with a sense of accomplishment.

The movie was filmed almost entirely on location in the places the action was set. Director Tom Putnam credited his background as a documentary film director for making this feasible. He said, "Because of my documentary background, we were able to construct a film that used a small crew to reach locations larger films could never go to...If you see David [Cross] hanging off a cliff, braving a thunderstorm, or struggling in freezing water, that's really him. When you see lava tunnels deep underground, that's where we shot."

The film was released virtually on September 18, 2020, due to the COVID-19 pandemic. The film's website noted that some of the film's proceeds would be donated to "protect wildlife and wild places."

Writing for The Hollywood Reporter, critic Frank Scheck called the film "awfully entertaining" and praised Cross's "touching and funnily self-effacing turn." The Austin Chronicle's Richard Whittaker praised the film as "a beautiful, quiet, lyrical, funny wilderness trip, a meditation on loss and picking up the pieces, and the most perfectly poignant performance of David Cross' acting career."
