The cover art of this Fawcett Crest edition of Breakheart Pass seems – in terms of style and composition – to have been created by the same artist whose work appears as the cover illustration of the 1963 edition of Ice Station Zebra.
(But, I don’t know who!)
Also adapted for film, the cinematic version of the novel, directed by Tom Gries, was released in December of 1975. Curiously, akin to Ice Station Zebra, while the novel itself has received highly favorable reviews at GoodReads (albeit far fewer than the for Zebra), the movie’s Wikipedia entry indicates that the film was a “box office disappointment in the U.S.”
You can view the film’s trailer (rather lengthy, at over three minutes) below, care of HD Retro Trailers, while you can listen to Jerry Goldsmith’s musical score, care of Soundtrack Fred, here.
Hmmm. The trailer does seem to impart a “TV movie” feel to the film…
