From Borys Kit on The Hollywood Reporter:
Disney is developing an adventure movie project inspired by the Matterhorn ride and has set Jason Dean Hall to pen the script. Justin Springer (Tron Legacy, Prom) is producing the project, which has a working title of The Hill.
The Matterhorn, also known as the Matterhorn Bobsleds, is part of Disneyland’s Fantasyland section. Opened June 1959, the elaborate ride was inspired by Walt Disney‘s desire for a toboggan-themed roller coaster as well as thoughts he had after an extended trip to Switzerland, the site of the famed mountain. The ride, a centerpiece of the park, was refurbished in 1978, with one of the upgrades being the addition of three automatronic Abominable Snowmen (aka Yetis) who growl at riders.
The idea behind The Hill is to do a thrilling, fast-paced movie centering on five young adventure seekers who, for mysterious reasons, are called to the top of the mountain and encounter a Yetis on the journey down.
