Originally titled "The Eye Creatures," the studio decided to rename the film "Attack of the Eye Creatures." However, when the title card was re-done to add "Attack of the" and then re-shot to edit it into the film, it was discovered that an additional "the" had been added, thus making the film's title "Attack of the The Eye Creatures."
Apart from the usual stock themes, director Larry Buchanan borrowed from The Hypnotic Eye (1960) an early scene in a bar featuring the same tune Yvette Vickers danced to in Attack of the 50 Foot Woman (1958).
The same "Eye Creature" costume later turned up in the AIP release The Ghost in the Invisible Bikini (1966).
Filmed in and around Dallas, TX, in 1965. At the 43:14 mark in the film, you see the O'Neal Funeral Chapel. It was this mortuary that two years earlier supplied the casket/hearse to transport the body of assassinated US President John F. Kennedy from Parkland Memorial Hospital to Love Field/Air Force One for the flight back to Washington , DC; cast listings do not confirm if it is actually Vernon O'Neal [who packed JFK's body for shipment] playing the white-coated funeral director. The Cadillac hearse that was used still exists and was recently offered at auction for $900,000. Earlier in the film you briefly see an O'Neal ambulance--possibly the same one [vehicle #605] that transported Lee Harvey Oswald's body to Parkland when he was shot and killed by Jack Ruby. That vehicle is also in a private collection.
This was one of a group of films shot in 16mm and color and used to pad out one of American-International's television syndication packages.
