There's a bit more to it than that...
I'm aware of at least three alleged alien videos. One is the famous "Alien Autopsy." Both of the other two are allegedly videos showing the interrogation of an alleged alien. Take it from me: none of the three videos show the same "alien."
The AA alien is looks like an average human with the following modifications: six digits instead of five, eyes twice as large as normal and with black lenses covering pale eyes, a severely bloated stomach, its head looked slightly bulbous and its arms and legs were unusually proportioned, and also other, smaller modifications such as the size of the nose and the placement of the ears. I would add that it had a gaping wide mouth but this (if somehow the footage was real) would have been due to the fact that after death the tongue swells so the mouth opens. This film looks completely believable to me, SAVE FOR TWO MISTAKES: 1) a telephone is visible, of a type not available yet in the late 1940s. 2) The person conducting the autopsy is too careless in his/her treatment of the "alien's" organs to be a professional.
The second video, of which you have been discussing here, proposes to show an alien being interviewed. Regardless of its authenticity, the alien in this video is not the same as the one allegedly depicted in AA. This alien is much smaller, has tan-colored skin, very large eyes (that, I would add, are not so large as to prohibit the presence of a brain, and are not so large as to overlap each other in the skull). I have only seen two stills from this video. The alien is only visible from the chest up. The scene is extremely shadowy, in my opinion. Although there exists the possible explaination that the alien did not like the light, it might also be that the lights were dimmed to make sure nobody realized the alien was a puppet.
The third piece of alleged alien film footage was one I saw on a now-cancelled show here called "Strange Universe." By far it is the least clear of them all. Like the other two, it was also shot in the dark. The alien (which has a huge head) is apparently wearing a black suit because although the film is shot at a distance sufficient for a view of most of the body, only the head and hands are visible; the rest disappears seamlessly into the blackness of everything else. The alien looks like your typical Grey: big head, pale skin, and big, black, walnut-shaped eyes. Not much else is discernable (does anybody out there know when night-vision fil became available? Sheesh!)
I should mention that there is a fourth film. Anyone who sees it will be astonished and instantly proclaim it to be the smoking gun of smoking guns. Had not the people who made it come forward and announced that they had filmed it and everything was fake, I would still be studying it today.
In this film, which is shot in a well-lit environment, an alleged abduction occurs. The film begins with some people walking in the forest, at night filming their trek with a video camera. Remember the UFO scene from the beginning of E.T.? Well, that's what happens next. Behind some trees lights appear and there's some strange noises and the people get really freaked out and run home. They get back inside and tell the family about what they'd just seen. Just then a Grey (yeah, a Grey: black, skin-tight suit, big head, gray skin, big black eyes -- the typical Grey) walks in with some sort of device in its hand that it points at everyone. Everyone screams. Yadda yadda. Another Grey enters. And then that's the last I can remember of it. Anybody who's seen it knows how impressive it looks. Even though it is a fake, it really is something to see. I haven't seen it in years, though.
