 WILHELM SCREAM: Can be heard four times in the film. When the giant  ants attack the crew of the ship at sea, when  James Whitmore (qv)s character Police Sgt. Ben Peterson is  throttled to death by a giant ant, when a soldier is struck by the  falling debris in the sewer and when James Arness gets separated  from the rest of the Army and ants try to attack him. The ceiling  falls in and while he doing something to his weapon, an ant tries to  attack him.
