Corrected entry: When entering the nest in the desert, it was important to wait until the heat of the day to insure that all the ants were inside. When entering the sewers in Los Angeles, they did so at night.
Corrected entry: When they are in the police Captain's office, he picks up the bent rifle that Gramps had. He says that Gramps got some shots off before they did that to the rifle. Then he says that "Blackburn was a crack shot, he could hit anything he could see". Gramps' last name was Johnson. The cop that got killed was Blackburn.
Correction: It isn't a character mistake; rather, the Chief was talking about two different facts here: That Old Man Johnson got four shots off with his Winchester; and then referring to Blackburn's gun skill as a police officer. Upon first hearing, though, this does sound like he was talking about the same person.
Corrected entry: When the radio operator on the 'Viking' is calling for help, an officer can be seen in the background standing calm and rigid in the middle of a pack of giant ants overpowering the rest of the crew...
Correction: Rather than the officer "standing calm and rigid", he's supposed to be dead and being held by the mandibles of a giant ant.
Correction: Yes, but they were also trying to rescue the two boys who were lost in the ants' nest. So it was important to hurry.
