Review: A spaceship returning from Mars brings with it a deadly infectious disease - 'blood rust' - which breaks out from the lab in the shape of Lyn Thomas, a latter-day Typhoid Mary abroad in the land without knowing the danger she presents. Edward Bernds uses 'documentary' style narration and clips to maintain the feel of the film and the whole is a fascinating movie that echoes future frighteners such as The Andromeda Strain. Moe Howard has a cameo as a cabbie. Never released to TV syndication. B/W Widescreen, in English, no subtitles. Quality C
