National Geographic Ent. has picked up The Wildest Dream, the story of George Mallory who was obsessed with becoming the first person to reach the peak of Mt. Everest.

According to Variety, The Wildest Dream is directed by Anthony Geffen and produced by Geffen and Claudia Perkins, with Mike Medavoy exec producing. The story is told through the explorer's letters to his wife, Ruth; previously unseen photos; and film from 1924 and from the 1999 expedition led by Conrad Anker, who found Mallory's body on Everest.

The Wildest Dream is narrated by Liam Neeson, with the voices of Ralph Fiennes as Mallory, the late Natasha Richardson as Ruth Mallory, Hugh Dancy as Mallory's fellow climber and Alan Rickman as the last person to see Mallory alive.

Mallory is remembered as having said, "Because it's there" in reply to the question "Why do you want to climb Mt. Everest?" He and his climbing partner disappeared in 1924; they were 800 feet from the Everest summit before the clouds closed in.

NGE said the film is dedicated to Richardson.
