VIDEO Meet the hero of Fantastic Beasts
The film was born out of a tome which originally appears as a textbook in the early Harry Potter books. It recurred a couple of times in the first few novels before emerging as its own book in 2001 written by the fictional Newt Scamander about the creatures he has seen through his many travels.
That means Scamander himself has been in author J.K. Rowling's head for almost two decades, which was certainly a help when it came to sitting down to pen the script for the all new film which featured a younger version of the character as played by Oscar winner Eddie Redmayne.
