It also features Hugh Beaumont, before he became The Beaver's dad and everyone's ideal TV father.
And it also has British actor Robin Hughes. In May 1941, Hughes was serving as an enlisted man aboard the British battleship HMS Hood. He was accepted for officer training and left the Hood to begin officer candidate school the day before it left port to pursue the German battleship Bismark. In the ensuing battle, The Hood was blown up and over 1,400 of its crew were killed. There were only three survivors, or as Hughes later said, "four." Quite a lucky fellow, that Robin Hughes.
I actually remembered before about Hugh Beaumont being in this film and from the show " Leave It To Beaver " as character Ward Cleaver .
Surprisingly I didn't remember that actor John Agar was the first husband of young actress Shirley Temple or that he was in this film ( was never overly familiar with this actor - but will be a real treat to see him in this film again ? ) .
According to Wikipedia he was also in the movie " Tarantula " from 1955 which has also been on The Svengoolie Show ( and have seen too ) .
The trivia section says that the humps of the mole people were created by stuffing the backs of the actors playing them with newspapers. I wonder if that was the idea of the wardrobe department or the special effects department?
