Right. There is a lengthy story behind how this movie came about. Originally, “Planes” was going to be a dvd-only sequel to “Cars,” and was going to be made by Pixar. Instead, Disney decided to release “Planes” in theaters. So, it’s not made by Pixar, but has a loose connection, in that it’s inspired by “Cars” by Pixar.
For information’s sake, Pixar’s next film is “Monsters University,” in theaters in June.
