(At around twenty-four minutes) The script for this movie makes no mention of Professor Flitwick. Wanting to keep Warwick Davis involved, Alfonso Cuarón came up with the idea of having him play the choir director. Mike Newell liked the look of the choir director, and wanted to keep using it. Therefore, the choir director became Flitwick, and his new look has been used for all of the subsequent movies.
