Don't worry, the world isn't actually going to end tonight (we're pretty sure), however this show will feature academics evaluating how and if this could actually happen. Humans have been predicting the end of the world for about 5,000 years or so, and as you may have noticed, we're all still grand. It's been the subject of many a blockbuster down the years - from Bruce Willis nuking an asteroid to John Cusack outrunning a super-eruption, but how could it all go if we were actually faced with Armageddon? This one-off programme explores Hollywood's most spectacular doomsday scenes, reveals the facts behind the science fiction, and counts down 10 of the most likely outcomes.
