Third Man on the Mountain

Third Man on the Mountain is a 1959 American Walt Disney Productions film set during the golden age of alpinism about a young Swiss man who conquers the mountain that killed his father. It is based on Banner in the Sky, a James Ramsey Ullman novel about the first ascent of the Citadel, and was televised under this name. The movie inspired the Matterhorn Bobsleds attraction at Disneyland Park.

The extraordinary difficulty of making this film on the Matterhorn was chronicled in the Perilous Assignments episode of Walt Disney Presents.
