Set in New York seven decades before the start of the Harry Potter saga, Fantastic Beasts is based on the Hogwarts textbook of the same name and follows the adventures of its author Newt Scamander, set to be played in the film by Oscar winner Eddie Redymayne. Scamander is described as a "magiczoologist" - or someone who studies magical creatures. Besides the lead, Warners are looking to cast four other key roles - two American girls and two American boys.

David Heyman will produce the movie, with Potter author J.K Rowling penning the script and David Yates directing.

"Although it will be set in the worldwide community of witches and wizards where I was so happy for 17 years, 'Fantastic Beasts and Where to Find Them' is neither a prequel nor a sequel to the 'Harry Potter' series but an extension of the wizarding world," Rowling explained.

Miller has a new movie, Trainkwreck, coming out next month.

Fantastic Beasts and Where to Find Them is set to bow on November 18, 2016.
