C&L's Sat Nite Chiller Theater: 'A Boy And His Dog' (1975)
Harlan Ellison hated the (added) last line of this movie...
Late in 1974, somebody (possibly still drunk from our long, national, Watergate bender) thought Harlan Ellison's post-apocalytic, science-fiction/horror/black comedy novella, "A Boy and His Dog", would make a terrific movie. It hit America's theaters in November, 1975 and then promptly disappeared into America's sketchier art-houses and science fiction convention all-night movie marathons.
It gave a young Don Johnson's career a big boost, keeps the novella's punchline intact, but adds final line of dialogue which Harlan Ellison described as a "moronic, hateful chauvinist last line, which I despise."
