The Hollywood Reporter has posted some of Seth Engstrom’s (Avatar, Tim Burton’s Alice In Wonderland) spectacular concept art from Summertime Entertainment’s forthcoming animated musical, Dorothy of Oz. The film’s all-star cast had already been announced – it includes Lea Michele (Glee) as Dorothy, Dan Aykroyd (Yogi Bear as The Scarecrow), Kelsey Grammer (The Tin Man), and Jim Belushi (The Lion). They’re saying the film will be released April 2012, but no distributor is attached. Is it in production? If so, where? What studio? We know it was developed at Ken Duncan’s Duncan Studios in Pasadena and that Dan St. Pierre (Everybody’s Hero) is aboard to direct. If any of our readers have the scoop, we’d love to hear more about it.
