Visible crew/equipment: When the bees attack the school outside, a crew member can be seen pointing to the ground for the actors to fall down dead.
Visible crew/equipment: During the Houston burnout scene, the flamethrower team set a car on fire. You can briefly see a film crew member rushing up with water to put it out.
Continuity mistake: The burnout of Houston takes place at nighttime, but when the bees attack an ambulance driver who then crashes into a building, the scene changes briefly to broad daylight.
Mayor Clarence Tuttle: I know people look at me and think that I'm just the man behind the aspirin counter, but inside I love you.
Maureen Schuster: How lucky I am.
Trivia: Irwin Allen was so disheartened by the amount of money he lost on this film that he forbade any of his employees to ever mention it again, and even cut short an interview when a question was asked about it.
