Screenwriter-turned-comic book publisher Andrew Cosby and Johanna Stokes have been hired to do a rewrite on Walt Disney Pictures' First Ascent, according to The Hollywood Reporter.

The film is described as a supernatural action adventure that revolves around a group of climbers who, while attempting to ascend a mountain in Bhutan, are attacked by an unseen beast.

Disney's Animal Kingdom in Florida features a roller coaster ride, "Expedition Everest," that includes an encounter with a yeti, though Disney said that First Ascent is a rewrite of an older project and is not related to the ride.
