"Night of the Lepus" It's about giant rabbits that are about to take over the world. It was made as deadly serious. --yes really was. The best bit is a scene at a drive-in movie where the hero makes an announcment over the sound system along the lines of "there's a herd of giant rabbits coming this way! Everybody turn on your head-lights, we have a plan!" All the lights are turned on, no questions asked!
