Scenes from ONE MILLION YEARS B.C. (1966)
This movie is known for two things: Raquel Welch in a fur bikini and the dinosaurs effects by Ray Harryhausen. But the movie also has one of the best disaster endings ever: a volcano erupts and complete mayhem ensues. The destruction is pretty thorough. The volcano shot above is obviously a model thanks to the painted background but the shot below is spectacular.
