SHOW PRODUCTION: Executive Producer Diane Masciale has a long history with overseeing news magazine content. 20/20 asked her to put her years of experience to work to when it decided to produce a one-hour program detailing the harrowing tale of a midwestern town’s encounter with one of the most powerful tornadoes on earth. As Executive Producer of the prime time hour with anchor Sam Champion, Masciale coordinated the highly produced, dramatic hour that told the story of several families who faced the massive EF5 twister as it tore through their town. The complex video sequences and high impact interviews made “Blown Away: Twisted Terror” a 20/20 season favorite.
