K2 (1991)
K2 is a 1991 motion picture loosely based on the story of two friends' ascent of the second-highest mountain on Earth, K2. The story is based on a play written by Patrick Meyers and presented as a senior-thesis at Stanford University. These roles were played by Michael Biehn and Matt Craven. The film was directed by Franc Roddam and written by Patrick Meyers and Scott Roberts, adapting the original stage play by Meyers. The two main characters of the film, Taylor Brooks and Harold Jameson, are loosely based on Jim Wickwire and Louis Reichardt respectively, the first two Americans to summit K2 in 1978. Wickwire and Reichardt are acknowledged in the ending credits.
