Not a prequel to K-9, but still a dog in every other sense. The story, adapted by Patrick Meyers and Scott Roberts from Meyers’s play, is basically an exercise in mawkish pretension with some pretty scenery, about two Americans (Michael Biehn and Matt Craven) who join an expedition to climb K2, the treacherous northern Pakistan peak. Franc Roddam directed, and Raymond J. Barry, Hiroshi Fujioka, Patricia Charbonneau, and Luca Bercovici costar. (JR)
