Sofia the First centers on a young girl whose life changes dramatically when her mom marries the king and she is suddenly whisked off to live in a castle. There, she must learn what it's like to be a true princess.
Grey's Anatomy star Sara Ramirez lends her voice to Sofia's mom, Queen Miranda, while Wayne Brady (Whose Line Is It Anyway?) plays one of the cute woodland creatures who hangs around the castle and Project Runway guru Tim Gunn voices Baileywick, the castle's royal steward.
Nancy Kanter, Senior Vice President, Original Programming, and General Manager of Disney Junior Worldwide revealed the trailer during the Las Vegas Licensing Expo earlier this week. Sofia the First debuts this fall as a primetime television movie on Disney Channel, followed by the series premiere in early 2013.
