Clockwise from Top to Bottom: Jay, Carlos, Evie, Mal
According to the write up on Entertainment Weekly, the infamous villains have been exiled on an island prison called Isle of the Lost. Twenty years later, Ben (son of Belle and Beast) decides to grant the children of the villains an opportunity for redemption. The four chosen are placed in a prep school with other offspring of Disney heroes and heroines. Whether they carry out their parents' evil plans or forge their own destinies is up to them.
The film stars Dove Cameron (Liv and Maddie, Cloud 9) as Mal, daughter of Maleficent (Kristin Chenoweth of Wicked and Pushing Daisies), Booboo Stewart (The Twilight Saga, X-Men: Days of Future Past) as Jay, son of Jafar (Maz Jobrani of Better Off Ted and the Axis of Evil Comedy Tour), Sofia Carson (Faking It, Austin & Ally) as Evie, daughter of The Wicked Queen aka Snow White's Step Mother (Kathy Najimy of King of the Hill and WALL-E), and Cameron Boyce (Jake and the Neverland Pirates, Grown Ups) as Carlos, son of Cruella de Vil (Wendy Raquel Robinson of The Steve Harvey Show and The Game).
It is directed by Kenny Ortega (High School Musical, Michael Jackson's This Is It) and is expected to air on the Disney Channel sometime in 2015.
