• When this movie was first released in Sweden, it was strangely named 'The Spiders'
• Was originally supposed to be filmed in color. Two days before shooting began a nervous studio cut the budget and the film had to be made in black and white.
• It was also supposed to be in 3-D. Some elements of the 3-D effects, such as the ants having extreme close-ups and the flame throwers shooting straight into the camera, were used in the film.
• This was Warner Bros.' highest grossing film of 1954.
• The flamethrowers used in the movie were standard World War 2 weapons and were loaned by the US Army. The actors handling the weapons were WW2 combat veterans who had actually used them in battle.

  Further evidence that the film was intended to be shot in 3-D can be seen as the scientists fly over the ant mounds in a helicopter. Joan Weldon is seen taking still photos using a Stereo Realist 3-D camera. When the photographs are being examined later, the scientists are looking at slides in a Stereo Realist viewer.
