WHEN  I WAS A KID IN THE EARLY 1960'S I READ AN ARTICLE IN SOME MONSTER MAGAZINE THAT THERE WAS 4 MILES OF WIRING IN THIS CREATURE AND IT TOOK 3 TECHNICIANS TO OPERATE IT. I CONSIDER THIS ONE A CLASSIC. SURE, THE DIALOGUE IS PURE "B" BUT THE EFFECTS AND STORY ARE GREAT. THE SCENE WHERE THE LOCK OPERATOR GOES OUT ON THE LEVEE AFTER HEARING SOME SPLASHING IN THE WATER AND IS ATTACKED FROM BEHIND, STILL MAKES ME JUMP. I RECENTLY READ THAT THE MONSTER PROP WAS PLACED AT THE ENTRANCE TO SOME AMUSEMENT PARK IN CALIFORNIA AFTER THE MOVIE WAS MADE AND IT'S ULTIMATE LOCATION IS UNKNOWN..........TOO BAD!
