The Boy Who Lived

The Boy Who Lived is an unproduced episode, originally going to be shown in Series 4, before the show was cancelled. This would've had Harry Potter and Lord Voldermort as actual people, before being explained as something which made them come alive from a screen. It was originally going to be episode one of Series 4, replacing the concept of Detective Beginner. However none of these two were produced, instead replaced by 2012.
