The lame 1950s B-Movie "Killers From Space" starring the hunky Peter Graves gets re-dubbed as a plot by aliens to turn Earthlings gay. What's interesting is that the guys who directed this are straight, so there are shots taken at everybody with equal derision. There's something in this for everybody! The visual and verbal gags come at breakneck speed so even if you find that 60% of the jokes are funny, you'll still be laughing several times a minute. It's zaniness at its most extreme (my favorite scene was a hilarious modern alien dance that included great reaction shots by the cast of the 1950s film), so be prepared to put yourself in "silly" mode. Those who hate the slickness of Hollywood films today will especially love this.
The DVD also has some nice features including some very funny commentary.
