Instant monster, just add water

[HoshiRyo]

I remember the vague outline of the plot, and that it used to be an apparent favorite for Encore's SF/Fantasy channel to run on Fridays, so it'd turn up on the free channel too.

The plot was a bit of a trainwreck.

1. Monster bones are found.  If I remember correctly, in the open, though I think that precisely where was in part I kept missing.

2. Two mad scientists, one with a daughter whose mother went insane, argue over possession.

3. The one with the daughter is trying to make a vaccine against insanity using the monster's bones, with the end result of the vaccine driving her insane, and her and some guy falling from a height.

4. Turns out that when the monster's bones get wet, you get an instant monster.  Yes, yes, the bones had been out in the open and all.  I didn't say this was a good movie, okay?

5. Monster chases everybody worth remembering of the characters down, they go insane, movie ends with them in the asylum and us left thinking that oh, it was just the rantings of a madman...

6. ...except the monster is, apparently, still out there.

I really do want to know the title, if nothing else so I can rewatch it and maybe review it.  It was The {something starting with a C} Terror/Insanity, I think.

The Creeping Flesh with Sir Christopher Lee and Peter Cushing.

One of the more underrated British horror flicks in my opinion. I caught it on PBS when I was a kid and it really creeped me out. I'm glad I splurged and got the (now out of print) DVD of the movie after its initial release. Thanks for reminding me that I have it... think I'll watch it tomorrow night after work.

Bereft of confirmation from O.P., Jordan and Trevor agree this is THE CREEPING FLESH, a film I watched several months ago, thus also confirm that it matches the O.P.'s description in every regard. Cushing and Lee are the doctors (of course), Cushing has a daughter, her mother was infamously psychotic, they find bones and revive them w/ water, Cushing is institutionalized by Lee at the end, the monster is sort of forgotten about (either didn't actually exist or just wanders off to parts unknown). The film looks okay and the acting is GREAT (Lee is better than usual) yet it is one of the stoopidest/most senseless gothic horrors in film history. Yep, there's only one CREEPING FLESH. Definitely Solved.

I love this movie! It's oddly ambiguous, and of course Cushing and Lee are fantastic. Best horror team since Bela and Boris.

"Oddly ambiguous" is a nice way to put it!      MONSTER-A-GO-GO was mentioned in another thread, and although it is widely disparaged by most everyone, that's one that I personally consider "oddly ambiguous" rather than "preposterously absurd". :D
