Supervolcano is one of the best documentary dramas I have ever seen. It is produced by the BBC, who in my opinion are best in the world at making doco/dramas. This is no exception, it's simply STUNNING! The dvd cover gives a good synopsis of what this movie is all about.It says- “74,000 years ago, the last supervolcanic eruption plunged the world into darkness for 6 years, heralded an Ice Age and reduced the human population to the brink of extinction. The next promises to be equally devastating-and it is already overdue…” This movie is based on fact & the BBC have woven these facts into a fictional account as to what might happen if this super-eruption ever occurs within our lifetime. It's sobering, scary stuff, but fascinating also. They've presented this drama in a documentary style,using a virtually unknown cast. Some may say that this is a B grade movie, but frankly I've seen MUCH worse A list films! This is well acted. Combining this with great graphics, amazing footage & excellent visual effects, makes Supervolcano a winner!
