Photographer Ben Moon's short film and memoir, Denali: A Man, a Dog, and the Friendship of a Lifetime will be adapted for the silver screen by Max Winkler, with Charlie Hunnam playing the lead.

Spyglass Media Group has bought the adaptation rights of the short film. Max Winkler will be in charge of the screenplay and direction of the feature film. Charlie Hunnam will star in as well as produce, along with Bona Fide Productions’ Ron Yerxa and Albert Berger.

In 2015, Denali, narrated by Moon's dog as the title character, was released as a short film online and gathered millions of views. The 8-minute film directed by Ben Knight had described Moon's cancer diagnosis through the eyes of his dog. It won several festival honours. 

The Denali book was published in January and it was promoted as the story of "a dog, his human, and the friendship that saved both of their lives."
