At the end of the credits we see what happened to the amnesia-suffering Professor Gilderoy Lockhart. He has written a book titled "Who Am I?". His moving image on the book's cover wears a straitjacket, and hums the movie's theme tune.
The character "Mr Borgin" is listed in the end credits although he does not appear in the movie. He appears in two additional scenes on the DVD.
Thanks to all the staff at Kings Cross Station, London.
The film begins with some dark clouds, one of them moves aside to reveal the Warner Bros logo which zooms in then turns away out of the picture, some more clouds then move aside to reveal the film title shining a bit in the sunset.
