Tonight's Stinker: Port Sinister (1953)

Tonight's Stinker Port Sinister (1953) https://youtu.be/h6xdaa704IM?si=JRZRx7fako0R5z9k From a pretty bad print, it's too dark to see most of the time, & according to the IMDB, about ten minutes is missing.... Anyway... A scientist pitches this notion to some institute about an island that sank 200yrs earlier, but rises when there's heavy volcanic activity... And there's a treasure on it... Later on, the first mate of the ship he charters breaks into the scientist's hotel room, to steal a map.... The scientist walks in & gets clocked & wakes up in a hospital two states away.... He charters a plane to catch up, while the crew takes the boat, finds the island & the treasure, but it's guarded by a giant crab... Uh, so anyway.....
