To find the really creepy logos, you've got to go off-road. These aren't film companies that anyone has ever heard of (Hikon??). And perhaps it's just as well. Though their logos are cheesy and look sort of low-budget, they have a very high freak-out factor.
I couldn't believe this WAS Orson Welles, thought it was maybe a Welles impersonator, but yes, that's him. I don't know anything about a Rainbow Release. His career did sort of slide downhill at the end. Note how the zoom-in stops at a certain point. That's kind of like MY zoom-ins, where the camera suddenly goes "bzzzzzzzzt".
This whole thing is so weird! Who's that guy, that face that appears in the militant-looking ABC logo, the one with the eagle catching a lightning-bolt in its beak? This looks like the emblem for a white supremacist group. The Super Circus thing is just bizarre. It has a fall of Rome flavour to it. Pre-Howdy Doody, I think.
Again. "An Apple Film". Not sure about this one at all. Reminds me, for some reason, of Dodo, the Kid from Outer Space - maybe the very basic animation.
Red blobs in space? Yes, it's exactly the same.
There's a whole sub-genre of logos from Indian movies. These are quite spectacular, but in most of them nothing moves very much. It's a sort of tableau, with alarming or even freaky-sounding music and sound effects. This one actually has a form of animation in it, though it's strange. A white blob turns into a woman. By the way, if you ever watch any of those "scary logo" compilations with the sound off (late at night, when you really should be in bed), they are suddenly a whole lot less scary. Sound is about 60%.
This one shows up in EVERY scary logo compilation, and do you know what? IT ISN'T A LOGO. At all. It's just a shot at the start of a very old Wizard of Oz movie from 1914. I don't know how they can call it a logo, but it is very strange. So I'll include it. And I've run out of them anyway.
