Take a look at the practical and digital effects that brought eight natural disasters to life, from the apocalyptic events of "2012" to the biblical deluge of "Noah."

Hollywood has always been keen on disaster flicks. The genre is unique in the sheer size of the spectacles that must be created, with special effects teams building entire cities or worlds only to level them. In this episode of "Movies Insider," we break down the diverse techniques used to create extreme weather phenomena on the big screen, from miniature effects to shaky deck sets to a massive light and rain rig, and show you exactly what these effects looked like behind the scenes.

We do a deep dive into how "San Andreas" used CG to sculpt a deep fissure in the earth, providing the backdrop for The Rock's heroics, and how "The Impossible" recreated the 2004 Indian Ocean tsunami with real water, filming Naomi Watts' and Tom Holland's scenes in Europe's largest water tank.

Plus, see how "Mad Max: Fury Road" created a hellish sandstorm fit for George Miller's dystopian vision, how Darren Aronofsky brought the biblical story of Noah's Ark and the Great Flood to life with large-scale rain effects in "Noah," and how Paul W. S. Anderson's "Pompeii" made an exacting recreation of the ancient city only to later destroy it with a volcanic eruption, earthquake, and tsunami. And find out how "Into the Storm" made a fantastical fire tornado look believable and how apocalypse movies like "2012" and "The Day After Tomorrow" used groundbreaking special effects to imagine end-of-the-world scenarios.
