I have been studying the footage closely in upscaled high definition and have come to the conclusion that the video is 100% genuine. The subtle eye movement, the head movement and facial expressions could not be faked IMO.
In around the year 2000 the tape was shown to more than two dozen heart specialists around the world and they all said the same thing that the heart monitor on the table would be impossible to fake.
Also, the timing of the alien's arrival at Area 51 coincided with the Kalahari UFO incident where the South African air force shot down a flying saucer in 1989. If you look carefully at the alien you will see it has an injured left eye as well as bruising around the top of its head. Some people also believe it to be the famous J-rod alien (see pic below).
People might laugh when I say this, but I'm convinced beyond a shadow of a doubt that the footage is genuine and that is coming from someone who initially thought the video was a hoax. The first time I saw the documentary on VHS in 1997 I thought it had to be a hoax. I guess I made the mistake of listening to Rick Baker (professional make-up artist) who immediately dismissed the tape as a hoax without bothering to closely analyse the footage. You'd have thought a so called expert like that would have taken the time and effort to analyse the footage properly before jumping to conclusions. But instead it took an ordinary member of the public like me to find out the truth about the video by carefully analysing the footage frame by frame.

"In the Alien Interview documentary Rick Baker and John Criswell were both happy to brag that they could create a more realistic alien. Fine, well where is it? In the Men In Black movies? In that ridiculous Alien Autopsy footage? Show me a more authentic alien than the one in that interview. By all means if these make-up people are capable of creating a more realistic alien then show me, compare it, place it before the public."
