Ghost In The Invisible Bikini

Abducted from her bed by a gorilla (played by actor George Barrows in a gorilla suit), Lili (Deborah Walley) is taken down to the dungeon in Ghost In The Invisible Bikini.

Once there, Lili is tied (and gagged) on a log that's on a conveyor belt which leads to a buzzsaw.

Barefoot, and clad in her scant bed wear, Lili puts up a nice struggle as the log that she's tied to (and in a pretty elaborate fashion, too) slowly makes its way towards the churning buzzsaw.

I remember being mesmerized by this scene when I first saw it as a kid. Everything it about it is great, from Lili's struggling, to the fact that she's barefoot.

The scene is actually played for laughs, as the collected heroes and villains battle each other while Lili is threatened by the buzzsaw.

She literally travels back and forth, away from the buzzsaw and then back towards it, as the heroes and villains take turns throwing the switch that operates the conveyor to save her and kill her.

I'm not sure how much of a Halloween treat this flick can be, as the supernatual element is very slender, and the film is not very scary at all--unless you really enjoy silly, kitschy comedies. But the BF bondage scene makes it worth it for me.
