Atlantis: The Lost Continent (1961)

I remember seeing this film as a 14 year old in 1961 at a Saturday afternoon matinée...my brother and I were supposed to go to a Detroit Tiger baseball game but it was rained out...what to do? We went to see this movie and I have always remembered it and loved it. Back in the late 50s, early 60s Hollywood was putting out a lot of science fiction fantasy films, like "Seventh Voyage of Sinbad", "Jack the Giant Killer", "Mysterious Island" and all of the sword and sandal Hercules movies with Steve Reeves and other musclemen. What could you not like about this film as a kid? A beautiful princess, a submarine in the shape of a fish, giant monsters fighting our hero in a fire/water pit, animal men with bull heads and horns, a giant sea monster Neptune showing our hero and his princess through the pillars of Hercules on their way to Atlantis and plenty of evil sorcerers and villains. A good love story to boot with our hero Demetrious winning the love of his lady Antillia and getting out of Atlantis just before the submerging and destruction of the mythical land. Edward Platt who was on the TV show "Get Smart" as the chief in a role as a minister/prophet who foretells the doom of the fabled continent. I fell in love with Joyce Taylor, the princess Antillia way back then....only problem is that our hero, played by Anthony Hall looked like he could have used some time in the gym training with Steve Reeves. On the very thin side for a hero to fight giants and evil rulers. Great science fiction stuff for the 60s.
