20th Century Fox and Walden Media have released the first trailer for The Voyage of the Dawn Treader, the third installment of the CS Lewis The Chronicles of Narnia series. What is interesting about this trailer is how much the Michael Apted-directed film seems in the wheelhouse of the family film platform now being followed by Disney picture chief Rich Ross. After the last film disappointed–its battle theme didn’t turn on the family crowd the way the original film did–the last regime at Disney punted the project. The filmmakers overhauled the series to trim the budget and tried to return to the magical themes of the first hit film. The film opens December 10. It was shot in 2D and converted to 3D.
