The term "Elvis sightings" refers to the conspiracy theory that Elvis Presley did not die in 1977, but went into hiding for various reasons and is still alive. This notion was popularized by the books of Gail Brewer-Giorgio and other authors. Several people even claim to have seen Elvis after he was supposed to have died. The earliest known alleged sighting was at the Memphis International Airport where a man resembling Elvis gave the name, "Jon Burrows", which was the same name Elvis used when booking hotels. A series of alleged sightings took place in Kalamazoo, Michigan, in the late 1980s. Such reports encountered much public ridicule and became fodder for humorous publications like the Weekly World News.
Elvis was rumored to have appeared in the background of an airport scene in the 1990 film Home Alone. The claim is that a bearded man wearing a turtleneck and sports jacket are over the left shoulder of the Catherine O'Hara's character when she is arguing with an airline employee. Paranormal researcher Ben Radford answers the Elvis sighting believers with the questions, why fake your death and then turn up as an extra in a popular movie? How could the cast and crew "have failed to notice the presence of one of the most famous figures in the world?" Even if he looked very different could he have disguised his voice and mannerisms? Radford was challenged to find the extra who played that part to prove it was not Elvis. Radford explained that the burden of proof is on the person making the claim, besides even if that specific extra was identified then how could it be proved it was not someone hired to pretend to be the extra? He suggested that ten extras should be chosen at random from "equally prominent ... scenes and see how easy they are to identify after all this time." In an interview with USA Today, director Chris Columbus responded "If Elvis was on the set, I would have known".
Bill Bixby, who co-starred with Elvis in Clambake and Speedway, hosted two television specials investigating the conspiracy: The Elvis Files (1991) and The Elvis Conspiracy (1992). The conspiracy was also featured in the 1990 video game, Les Manley in: Search for the King, where the titular hero attempts to find Elvis (known in-game as "THE KING" in all-caps) in order to win a million dollar contest.
