Need Help Finding Title of Monster Film
I recall seeing an old monster movie that starts off with an oil-derrick crew encountering some unknown flesh (while drilling) which then begins to regenerate in a laboratory water bath (of some type) while scientists try to identify it. It eventually grows into a large monster, which is killed in the climax (natch!), but the last scene is of one of its lower legs standing upright on the ocean floor and shaking slightly - suggesting that it has already started to regenerate ... into another instance of the monster!
Any ideas of this movie's title?
Thanks for your help! :-)
