IMDb has added Keri Russell to the cast of DisneyToon Studios’ Planes. Until an official confirmation arrives, one should take this bit of casting news with a grain of salt, since IMDb also still has Jon Cryer as the voice of protagonist Dusty Crophopper. In December, sources revealed Cryer had left the project for reasons unknown. His replacement has yet to be named. Planes will fly into theaters nationwide on August 9.
