Polygon's horror fans are back with the annual Halloween Countdown, a 31-day run of short recommendations for the best movies, shows, TV episodes, and online specials to stream for the Halloween season. Two non-Universal horror movies from this period make for a particularly entertaining double feature for fans of monsters and/or mad science: Doctor X from 1932, and Mad Love from 1935. Lionel Atwill went on to become a regular in Universal’s Frankenstein movies. Mad Love is less of a mystery: Any film starring Peter Lorre makes it easy to guess who the guilty party might be. Mad Love is available to stream for free at Fawesome, but bewaaaaaarrrrre a squashed, incorrect aspect ratio!
