The Impossible, which followed the story of a British family caught up--literally--in the massive tsunami that hit Thailand in 2004, earned Naomi Watts a well-deserved Academy Award nomination -- it couldn't have been easy to play a woman stuck by a branch in the breast and tossed around in the heaving water like a gasping tuna while her family gets carried off to parts unknown. Though Watts may have gotten the most attention of any aspect of the movie for her role, that tidal wave was practically a character in itself.
Director J.A. Bayona's masterful staging of it sure set the bar for water disaster movies to come--but how exactly did he capture the wave's massive scope, with toppling trees and entire houses carried away like so much cardboard? Check out this exclusive clip in which Bayona details what all went in to the tsunami scene, part of a featurette that will be included in the film's DVD and Blu-ray release April 23. The Impossible is available now on VOD.
