My husband is trying to find the name of a movie he saw when he was a kid. He saw it in the 70’s and he thinks it was a 1960’s movie. It was a little hookey, but he would like to find out what it was and watch it again. It was set on another planet that was swampy and the inhabitants would wear snowshoe type shoes and had balloons tied to them so they wouldn’t sink into the swampy water. It was almost like walking on water (but it was swamp). He can’t remember much other than that. Anyone have a clue???
