The Sun is reporting that Miriam Margoyles has told them that her character, Professor Sprout, herbology teacher, has been cut from the script for the fifth film 'Order of the Phoenix'.
Quote:
The award-winning actress said: "I am not making the fifth Harry Potter. They made a great mistake and cut my character."
This implies that the script is already under way which might make sense since the new screenwriter Michael Goldenberg was recently announced.
