A set of three images from the production set of “Fantastic Beasts and Where to Find Them” may have leaked online. Meanwhile, the producers have issued an open casting call to fill the role of a girl between the ages of 8 and 12.

Mark Wilson, who describes himself as an amateur photographer, posted this set of images from Hertfordshire, England, near Leavesden Studios of Warner Bros., the studio that is making the movie. He was unsure if the production set being built there was for the “Harry Potter” spinoff at that time. The confirmation about the photos came from Kitty Thornton, who is a fan of the franchise, in this tweet.

Thornton said she was at the location and that an employee of the studio also confirmed that J.K. Rowling inspected the set recently. Rowling will be making her screenwriting debut in the “Fantastic Beasts” movie. The set that she is said to have inspected includes a large gateway in one picture and a green screen in another.

Just as the “Harry Potter” movies found their stars with an open casting, the producers are also looking to cast the role of an 8 to 12 year old girl in the movie by inviting all interested applicants to meet the team in London. Warner Bros. made the announcement on its official website and said that the queue will open at 9 a.m. local time on Saturday and close at 1 p.m. 

The character being cast is described as someone who is “a haunted young girl with an inner strength and stillness. She has an ability to see deep into people and understand them.” Gregory Walton of the Telegraph is calling it the search for the “next Emma Watson.”

Watson got the role of Hermione Granger in the “Harry Potter” movies after thousands of girls auditioned for the role. The production of “Fantastic Beasts and Where to Find Them” is expected to begin soon and the movie is slated to be released on Nov. 18, 2016, in the U.S.
