Murder Rock

Nothing very special about this giallo. A bunch of dancers are trying out for parts, and some get murdered by a hatpin stuck into their left breast (where it looks like it would actually pierce a lung and not the heart as intended). Some of the dancing scenes are pretty sexual.

The studio where they do their dancing has a rather odd system at the end of the day whereby a voice comes over an intercom, and the lights flash on and off repeatedly. I guess this is to make for more suspense or to make the killing scenes more exciting? It's more on the annoying side.

One of the women has a dream in which she is pursued by a killer with a pin (it changes sizes throughout the dream, sometimes appearing giant). She later sees the man from her dream on a billboard. She tracks him down, finding him to be a bit of a washed up, alcoholic actor, and starts a relationship with him.

Much more than that I don't remember.
