Star Trek - The Original Series, Episode 20: The Alternative Factor [VHS]
"The Alternative Factor" is a minor episode in which Kirk encounters two versions of a fellow named Lazarus (Robert Brown), one from our own dimension and the other from an antimatter cosmos. The latter Lazarus intends to create an opening between worlds, potentially causing an intergalactic Armageddon. Though directed by Gerd Oswald, an interesting feature filmmaker from Hollywood, "The Alternative Factor" has to work a little too hard to make its point. Still, it isn't boring, and the theme certainly fits that long-standingStar Trekobsession with dualities.--Tom Keogh
