Perversidad

With the split screen there are two stories being told with 2 soundtracks. Frequently, the dialogue side is turned down so that it can't be heard over sounds from the other half. It's extremely annoying and reduces any interest in watching the rest of the film.

Was it that poorly mixed for theaters, too, or was this just a bad copy on TCM?

I was also amused by the organist playing some random mood music. We see the sheet music for the piano score for the 1925 PHANTOM OF THE OPERA, but the notes visible in some shots are not the ones being played. It may be legit Phantom music, but who knows for sure?

Other reviewers here have sufficiently summarized the rest of the film.

Movie takes place at a huge seaside hotel in California. In it handyman Jason (Randolph Roberts) attacks and kills blonde women. He then hides the bodies so they just go missing. The hotel has a security man searching for the people and beautiful Lisa James (Tiffany Bolling) is hired to sing there. She has black hair...but decides to wear a blonde wig which has Jason after her.

This was the first (and last) film shot in "Duo Vision"--basically a split screen used in 99.9% of the film (there are a few shots in the film not using it). It actually works pretty good sometimes. You see a person on one side of the screen and see what he's thinking of on the other. Still, it's just basically a gimmick to sell the film (it didn't work). The story itself is familiar and the killings are pretty non-bloody (this has a PG rating), but the acting itself is actually not half bad and the film kept my interest. Not a camp classic by any means but an OK film with a well-used split screen process. I give this a 7.

Wicked, Wicked is unique in that it is shot entirely in DUO-VISION (a gimmick of early 1970's cimena). Brian DePalma used this technique with great success in both Carrie and Phantom of the Paradise. The problem here is that Richard Bare is no Brian DePalma and the story is completely idiotic.

the one saving grace of this film is the moment at which the duo-vision becomes "uni-vision" during the climactic moment of the story. You have to see it to appreciate the greatness of that one shot. Perhaps the director came up with that idea and then made a whole story around it?

Filmed, using the modern miracle that is "Duo-Vision" (aka: split screen), WICKED, WICKED is about an enormous hotel, and the psychopathic killer that lurks there. Though it's obvious who the murderer is from the beginning, this movie is quite entertaining and even boasts a nice "shock" finale.

Rick Stewart is serviceable as the womanizing sleuth on the case, while Randolph Roberts is perfectly cast as the bug-eyed maniac. There's also a cavalcade of oddball characters and the hyper-intense Scott Brady in another hard-nosed, barking cop role. Watch for Roger Bowen as the sniveling, reputation-obsessed hotel manager.

Is this a classic film? Well, no, but it is a lot of fun to watch. However, you might have to watch it twice in order to avoid eyeball whiplash...

What I find so great about the horror genre is that, even though I've seen over 2500 films of different sub genres and numerous countries already, I keep stumbling upon crazy stuff nobody ever heard about. Even more incomprehensible – especially in the case of "Wicked Wicked" - is how come these movies are still so obscure and unloved? Now this certainly isn't a masterpiece of film-making, but nevertheless I would have expected a movie with such a peculiar gimmick to have some sort of loyal fan-base or at least enjoy some recognition at horror internet forums. Well, apparently not. "Wicked Wicked" remains underrated to this date, but hopefully a proper DVD-release will change that one day sooner or later. Make no mistake, however, the plot of this film is extremely rudimentary and straightforward all in favor of putting the emphasis entirely on the "Duo-Vision" gimmick. This is just a fancy term to say that the split-screen effect lasts throughout whole film. Unlike I feared, this gimmick isn't as irritating as I thought it would be, but nevertheless it's only truly creative in a handful of situations.

There are a couple of highly disturbing murders taking place in a fancy Californian seaside hotel. Beautiful blond women are brutally stabbed by a maniacal culprit and their bodies dumped around the hotel. Former policeman turned security agent is asked to investigate discretely, but the bodies keep piling up at a fast pace. The case gets more personal when his beautiful blond ex-wife arrives at the hotel to put up a singing show.

I don't really know why I bother to keep the killer's identity secret and even somewhat mysterious, because the film itself certainly doesn't. The culprit takes off his mask and exposes his face after the second murder already; probably to illustrate once more that the whodunit aspect of the film really wasn't the producers' main priority. And yet, despite this premature and regrettable revelation, there are multiple tiny plot components that are interesting and worth analyzing. For example, the sub plot about the hotel owner's reluctance to inform the police and his attempts to avoid negative publicity predate the similar "Jaws" plot with nearly two whole years. There's also a bizarre but engaging and original resemblance between this film's main characters and the ones from Gaston Leroux' immortal horror tale "The Phantom of the Opera". There's a pretty imaginative, yet typically rancid 70's and massively perverted twist regarding the culprit's motives to kill blond women near the end (which I really loved) and there's a neat supportive role for Spaghetti western regular Edd Byrnes as a moonlighting lifeguard. If you ever have the opportunity to watch "Wicked, Wicked" – and apparently it's occasionally programmed on TCM – please do so! It's far from being a great film, but it's definitely unique.
