On April 4, 2006, two days prior to the UK release of Alien Autopsy (a British comedy feature film on the subject of the footage), British Sky Broadcasting broadcast a documentary, Eamonn Investigates: Alien Autopsy, presented by Eamonn Holmes. In this program, Ray Santilli and fellow producer Gary Shoefield announced that their film was only partially real (a "few frames," in their words), while the rest was a reconstruction of twenty-two rolls of film, averaging four minutes in length, which Santilli had viewed in 1992 but which had subsequently degraded from humidity and heat. They said that only a few frames of the original were still intact by the time they had raised enough money to purchase it.[2]

Santilli and Shoefield stated that they had "restored" the damaged footage by filming a simulated autopsy on a fabricated alien, based upon what Santilli saw in 1992, and then adding in a few frames of the original film that had not degraded. They have not identified which parts are original footage.[2]

According to Santilli, a set was constructed in the living room of an empty flat in Rochester Square, Camden Town, London. John Humphreys, an artist and sculptor, was employed to construct two dummy alien bodies over a period of three weeks, using casts containing sheep brains set in raspberry jam, chicken entrails and knuckle joints obtained from S.C. Crosby Wholesale Butchers in Smithfield meat market, London. Humphreys also played the role of the chief scientist undertaking the examination, in order to allow him to control the effects being filmed. There were two separate attempts at making the footage. After filming, the team disposed of the "bodies" by cutting them into small pieces and placing them in rubbish bins across London.[2]

Alien objects, supposedly items recovered from the crash site, were depicted in the footage. These included alien symbols and six-finger control panels, which Santilli describes in the Sky documentary as being the result of artistic licence on his part. These artefacts were also created by Humphreys. The footage also showed a man reading a statement "verifying" his identity as the original cameraman and the source of the footage. Santilli and Shoefield admitted in the documentary that they had found an unidentified homeless man on the streets of Los Angeles, persuaded him to play the role of the cameraman, and filmed him in a motel.
