Ezra Miller is reportedly in talks over a role in the 'Harry Potter' spin-off.

The 22-year-old actor - who starred as the title character in 'We Need to Talk About Kevin' - is wanted to assume the role of Kredan in Warner Bros.' 'Fantastic Beasts and Where to Find Them'.

While it remains unclear how close the two sides are to agreeing a deal, Variety reports that Ezra is the studio's preferred choice for the part.

The much-anticipated new movie will definitely star Oscar-winning actor Eddie Redmayne, who'll be working from a script penned by best-selling author J.K. Rowling.

Speaking about the movie, the writer recently explained: ''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.''

Other crucial roles in the movie still to be cast include Queenie, Tina's younger sister, and Jacob, a rival of Newt Scamander's.

Alison Sudol is reportedly the first choice for the role of Queenie, while Josh Gad and Michael Cera are being considered for the part of Jacob.
