For "Prisoner of Azkaban," Cuarón assigned Radcliffe, Grint, and Emma Watson with some homework. They had to write essays about their characters' backgrounds. True to Hermione, Harry, and Ron, Watson wrote the most, Radcliffe wrote a few pages, and Grint just didn't do it.

The featurette comes from the 31-disc "Harry Potter Wizard's Collection," which will be available on September 7, but orders must be made by July 31, if you'd like to own the set.
