Spyros Melaris exclusively told Express.co.uk he would take a lie detector to prove once and for all that the film released in 1995 was a “pure hoax” and not based on any original genuine material.
The film’s producer Ray Santilli claimed yesterday the 1995 film was based on genuine footage.
But his claim has been refuted by Mr Melaris who maintains genuine footage did not exist.
Mr Santilli, who is CEO of Orbital Media Group, claimed yesterday that, although the 1995 film was made using actors, it was a “restoration” of original footage of the Roswell crash site and alien autopsy, that he had obtained, but it was of too poor quality to screen.
The film showed men in white coats apparently dissecting the alien, leaving UFO hunters convinced it was the smoking gun evidence they were looking for of the Roswell incident.
Truthers have been searching for proof since it was first claimed aliens crashed a flying saucer in the New Mexico desert near Roswell in July 1947 before the US Government covered up the evidence by storing the flying saucer and dead bodies in a secret military base.
It remains one of the world’s biggest conspiracy theories, but to the disappointment of alien hunters the 1995 footage was later exposed as an elaborate hoax.
Mr Melaris today hit back at claims it was a recreation of some unseen genuine footage, saying “none existed.”
He said: “I will also prove that there is no real 1947 footage. There never was. Mr Santilli has called this film a restoration.
“There was never any real film to restore. It isn’t even a recreation. It is a work of art.
“I would welcome a lie detector test alongside Mr Santilli. I hereby offer myself for such a test.”
The row comes as Mr Santilli claimed he has a still from “original 1947 poor-quality footage” possibly showing a genuine alien from the Roswell UFO crash.
British businessman Mr Santilli, 58, released the image after Express.co.uk reported on a one-man theatre show Mr Melaris is performing, in London in which he explains how the famous hoax was carried out.
In the show, Mr Melaris tells how the video was produced inside a north London flat, thousands of miles from the secret US base it was purporting to be in.
Cow and lamb organs from a butcher were used to represent those of the extraterrestrial.
In a previous interview with UFO researcher Philip Mantle, who exhaustively investigated the autopsy video, Mr Melaris said: “The question is did I make it from original film? And the simple answer to that is no. I’ve never seen any other film.
“Ray maintains that he’s got original film. My question to Ray is how would that film marry with what I made? It can’t. I haven’t actually seen the film.
“The story’s a bigger story if there was a real film. There would be more money in it.
“Why would I jeopardise being part of that and go off on my own? There’s no reason to. That’s the first thing.”
Mr Santilli responded insisting there was original 1947 footage that was recreated and he would also take a lie detector to prove it.
He said: “I am more than happy to do a lie detector test.
“In 2006 Spyros recorded an interview where you can hear him confirm that the footage existed and that he saw it.
“It was an interview that he gave to Adrian Sington a book publisher.
“I have no idea why Spyros would now wish to change his mind and rewrite the sequence of events.
“My story has not changed in over 20 years.”
Mr Melaris said that he was shown by Mr Santilli black and white film which appeared to show an alien inside a tent, but it had later emerged this was also shot in the 1990s.
He said: “There was never any original film other than the tent footage.”
He said of the interview with Mr Sington that he was referring to the tent footage, which was also fake.
Mr Melaris said: “I told him about how Santilli invited me to his office to show me the genuine article.
“I explained in detail what I saw… a genuine film… I later discovered this to be the tent footage and I knew this was fake. The excerpts they used were out of context.”
