Harry Potter and The Chamber of Secrets
The movie stars Daniel Radcliffe as Harry Potter, Rupert Grint as Ron Weasley, and Emma Watson as Hermione Granger.
If you wait until after the credits you will see a scene in Diagon Alley where Gilderoy Lockhart's new book is shown on a stand. The book is called "Who Am I?" and shows a picture of Lockhart in what appears to be a straight jacket.
