THE FROGMEN was fun film. I love the standard WWII movie, they're usually about airmen, armored cavalry or grunts, but seeing one about an underwater demolition unit is pretty unique. Honestly, I can't even think of another one off the top of my head. Strong (all male) cast, exciting underwater scenes, quick pace, Harvey Lembeck, Navy ships, explosions, heroism. Highly recommended for WWII Navy buffs.
If you pay close enough attention you'll see a young Jack Warden in a brief role (the sailor who spills water on Dana Andrews shoes) and Robert Wagner in an even briefer role (all he does is stand there and say "Aye aye, sir." to Gary Merrill).
In one scene a UDT guy swims onshore and plants a sign on the beach welcoming the Marines. I'm curious if anything like this ever happened in real life?
