Betamax obsessive Ray Glasser produced this Star Trek fan-film in 1971 for a class at Ohio State; it's a nice, corny piece of work. I really like the scenery-chewing acting, and as John at Neatorama pointed out, the sideburns and mustache for Spock are damned stylish.
This video was a final exam in a TV production class that I took at Ohio State back in the spring of 1971. Even as a lad of 21, I always had to have everything preserved!! I had this taped on 1" open-reel videotape, then transferred it to U-Matic and then to Beta. (I got an A-.)
