National Geographic presents an immersive new giant-screen film experience that brings audiences face to face with Mother Nature at her most dangerous. Traveling to Alaska’s melting glaciers, filmmakers capture the action as massive chunks of ice shear off into the frigid water with explosive force. In the Midwest, cameras roll as storm chasers risk their lives to capture data as deadly tornadoes race toward them. And in drought-ravaged California, filmmakers embed themselves with courageous first responders fighting to contain raging wildfires. Featuring insights from experts including National Geographic Emerging Explorer Dr. Erin Pettit and Oklahoma tornado researcher Justin Walker, EXTREME WEATHER dramatically demonstrates how climate change is rapidly affecting our land, oceans and atmosphere to produce natural disasters as ruinous as they are spectacular. The film unveils the surprising linkages between these three areas, demonstrating how a small change in one place can have large effects elsewhere. Directed and filmed by Sean Casey (“Storm Chasers”, “Tornado Alley”, “Forces of Nature”), EXTREME WEATHER showcases breathtaking cinematography reflecting Casey’s life-long immersion in the world of giant-screen nature documentaries. “I’ve always had a fascination with weather,” says Casey. “We wanted to go into the field and capture incredible imagery. The 150-foot flames, the 400-foot wall of ice falling, the tornadoes - there’s a majesty to all of that. The way I see it, EXTREME WEATHER lives at the crossroads of beauty and destruction.” The film is produced by Jen Casey. Narrated by Emmy Award®-winning actor Michael C. Hall (“Dexter,” “Six Feet Under”)
