The 3-D process used by the producers of this odd flick was called Nature Vision. Like most 3-D efforts such as "Comin' At Ya" and "The Man Who Wasn't There", the whole point of the exercise was the 3-D. In this, also known as 'Eyes of Hell", the 3-D sequences are pretty effective and trippy and quite bizarre. They also feel like they were shot for another film. The bridging story about a man receiving an Aztec mask is rather slow and ponderous and stylistically inert. But when the hallucinations occur, triggered by the mask, the imagery becomes psychedelic and surreal. There isn't much violence or bloodshed, but the use of the process is respectable. I saw this originally at a drive-in and I well remember the original, colored ad mat (red) that promoted the film's gimmick.

This movie really grows on you. Yes, it's true, the non-3D parts are boring, but I find them functional. Like any good freak-out movie, if it was all a freak out, you'd get worn out fast. This is like a freak-out musical in a way, where the freaky scenes are the equal of big musical numbers.A doctor is turned on to a creepy mask by one of his patients who has turned into a homicidal maniac. Next thing you know, the doctor is trying on the mask and going insane, and oh what a mess, and his girlfriend and everyone, and blah blah blah. Meanwhile, in the hallucinogenic mask sequences, you get to experience what it must have been like to be on LSD in the 60's. There's a whole "alternate world," where a strange, mutated man is milling around, looking for the woman (?) he is in love with in a fever dream landscape where there are skulls and burning hands and satanists and gore and other neato stuff. And it's all in bizarro 3-D! Even if it doesn't work well all the time, it's still mighty disturbing, especially for a movie from 1961! The images, and the incredible, collage-like soundtrack to the freak sequences will linger on your brain long afterwards, in the same way that wearing those horrible glasses leave an impression on your eyes after you take them off for the "normal" scenes. You're exhausted, and confused, and weirded out.Yay

This silly, stagy, slow moving horror film is probably still the best 3D movie ever made. Once you wait through the bland story, and the call comes to "Put On The Mask"; it becomes another film. These 3D sequences are the best, freakest ever put on film, and they transfer to TV remarkably well in the Elvira edition. If you have any taste for oddities at all, this is a must.

I actually saw this in a sticky-floored, popcorn-smelling old theater in about 1963 or '64, at age seven or eight. I believe it was the first 3-D movie I had ever seen. We had the little two-tone cellophane and cardboard eyeglasses and everything. What can I tell you, the dream or hallucination sequences made a big impression on me at the time. When I stumbled upon a copy of the Elvira-hosted version in the mid-'90s I snapped it up. It's actually in 3-D, and comes with the special 3-D viewing spectacles. I was a little let down. It all seemed so blurry and out of focus, and struggling with the glasses broke the mood. A couple of years later it was broadcast on one of the cable movie channels and I watched and taped it. I thought it was actually a little *better* without the distracting 3-D effects.
