TCM’s futuristic Fridays conclude tonight, with one last rundown of sci-fi movies, most showing dystopian futures. Here’s a particular favorite: a 1974 comedy-drama about a futuristic loner who roams dangerous territory with his telepathic, much smarter dog. The story comes from Harlan Ellison, one of my all-time favorite speculative-fiction writers – and the movie stars Don Johnson, a decade before he’d become a star on Miami Vice.
