The death of Leonard Nimoy last week has compelled me to keep digging up early footage of the original Star Trek cast before they set foot on the Enterprise. You may recognize the title, Science Fiction Theatre, because George McFly said it was his favourite television program in Back to the Future, but Science Fiction Theatre was actually a real anthology TV series which aired for two years during the mid-1950s. Over the course of the show’s run, DeForest Kelley got some of his earliest brushes with the genre which eventually made him famous by appearing in three different episodes.
