Behind the scenes
- In the PS2 version of Harry Potter and the Chamber of Secrets (video game), Punnet is credited as the wizard who wrote Hogwarts, A History. However, a later film prop identifies the book's author as Professor Garius Tomkink, and The Wizarding World of Harry Potter ultimately presents Bathilda Bagshot as the author.
