Trivia: Tony Gardner, special makeup effects artist was under investigation by Arizona State Police and Missing Persons bureau for effects work done on "Three Kings" involving a bullet traveling through a soldier's body.

The Missing Person's division thought that the "cadaver" was obtained by taking a homeless person off of the streets of Phoenix, Arizona. Eventually, Tony had to write a disclaimer describing how he had achieved the sequences with makeup effects technology so that Warner Brothers could hand or fax the disclaimer out to all of the people flooding their offices with inquiries.
