Dick Dial (Guard #2), Ray Didsbury (Crewman), Dennis Cross, George Sawaya, John Cliff, Peter Dixon, and Paul Kessler (Men)
Some editing at the beginning results in some confusion. When the invaders enter the Missile Room, the crewmen jump to the attack and are restrained by the officers. No shots are fired, no one is clubbed, knifed, or otherwise struck. After the opening credits, the scene returns to the Missile Room. If you look closely, you can see a body on the floor behind the men. A short time later, Chip Morton refers to "Henderson and Purcelli". Purcelli has been "taken away"--presumably killed; Morton is not certain about Henderson. The audience is left wondering.
Crane: We met the chief buccaneer, but outside of that, we don't know much.
Morton: Wouldn't he talk?
Crane: Talk? He won't shut up.
Logan: Congratulations. A brilliant maneuver. Well planned and cleverly executed. Even I couldn't have done better. Unfortunately, your victory is an empty one.
Curley: What's with him?
Crane: Be patient, Chief. If I know Logan, this is going to be a long speech.
Logan: You gentlemen will be the guests of a government which, in exchange for the gift of your submarine, will undoubtedly regale you with their own inimitable brand of Oriental hospitality.
Curley: Can't that guy talk English?
The scene of the guards hammering on the deck of the Seaview -- and then being tossed in the water during the crash dive -- is another clip from the 1961 Voyage movie.
