I read somewhere that Matheson, author of the book, did not like what they did to his book, and I have to agree.
Also, Ennio Morricone, composer of OVER 400 scores, including THE MISSION, THE GOOD THE BAD & THE UGLY, ONCE UPON A TIME IN THE WEST, ONCE UPON A TIME IN AMERICA, THE UNTOUCHABLES, DAYS OF HEAVEN, composed one of his finest scores for this movie and it was rejected for who knows what reason. Some 28 minutes of the score have surfaced and copies abound, so if you can get a copy, do so.
And I would recommend that you get a copy of Richard Matheson's novel and read it.
