Gracie Cochrane won’t be enrolling in Hogwarts this fall.

HBO announced that Cochrane will depart the upcoming “Harry Potter” series ahead of Season 2. Cochrane played Ron Weasley’s (Alastair Stout) younger sister, Ginny, in “Harry Potter and the Philosopher’s Stone.” Cochrane and her family attributed the “challenging decision” to “unforeseen circumstances.”

“Her time as part of the ‘Harry Potter’ world has been truly wonderful, and she is deeply grateful to [casting director] Lucy Bevan and the entire production team for creating such an unforgettable experience,” the Cochrane family said in a statement. “Gracie is very excited about the opportunities her future holds.”

HBO said they “wish Gracie and her family the best.”

“We support Gracie Cochrane and her family’s decision not to return for the next season of HBO’s ‘Harry Potter’ series, and we are grateful for her work on season one of the show,” HBO wrote in a statement.

The HBO series was greenlit for a second season in early May, months ahead of its Christmas Day premiere later this year. If the sophomore season follows J.K. Rowling’s second book, “Harry Potter and the Chamber of Secrets” (the first season is adapted from the first novel), Ginny will begin her first year at Hogwarts in Season 2.

Cochrane was cast following a massive undertaking by HBO to find young actors for the show. HBO reviewed more than 32,000 auditions before selecting Dominic McLaughlin to play the boy who lived. The cast was filled out with West End performers, like Arabella Stanton (Hermione Granger), first-time actors like Amos Kitson (Dudley Dursley) and longtime stars including John Lithgow, who will play Albus Dumbledore.

HBO Chairman Casey Bloys explained that they expected a lot of “interest” in the cast because of the cultural prominence of the “Harry Potter” franchise.

“Interest can tip over into more unpleasant and aggressive behavior,” Bloys told Deadline, alluding to racist backlash over the casting of Paapa Essiedu as Professor Snape. “We talked to them about what to expect … but any kind of security that’s needed is an unfortunate aspect of doing IP shows. We just try to be mindful and monitor it.”

In March, HBO released its first trailer for the show, which included a peek at the redheaded Weasley family saying goodbye to Ron at Platform 9¾ before he boarded the Hogwarts Express. The trailer also teased Harry’s acceptance letter from Hogwarts and his wand and Nimbus broom.

Don’t worry if your Hogwarts acceptance letter got lost in the mail — a new “Harry Potter” experience will soon let you hop aboard the Hogwarts Express anyway.

Harry Potter: A Hogwarts Express Adventure will open at the Southern California Railway Museum this summer for guests to experience the Wizarding World rite of passage aboard a real moving train in the Inland Empire. The experience will run from July 24 through Sept. 27. Yes, that includes Back to Hogwarts Day on Sept. 1.

A Hogwarts Express Adventure will include a Platform 9¾-themed preboarding experience as well as House competitions and chants, spell-casting challenges and other interactive activities aboard the train. Guests will also be able to grab some themed treats from the trolley. The train ride will end at a Hogsmeade-inspired village where more food, beverages and merchandise will be available.

The Rail Events Inc. press release also teases a possible encounter with “a dark and mysterious force.” The company, also known for the Polar Express Train Ride, developed A Hogwarts Express Adventure along with Warner Bros. Discovery Global Experiences.

This is a big year for “Harry Potter” fans. “Harry Potter and the Philosopher’s Stone,” a new television series based on author J.K. Rowling’s popular book series, is set to debut on HBO Max on Christmas Day. The show will introduce audiences to a new Golden Trio, portrayed by Dominic McLaughlin (Harry Potter), Alastair Stout (Ron Weasley) and Arabella Stanton (Hermione Granger), as they embark on their Hogwarts journey. (Rowling remains controversial for her views on trans women.)

Ticket sales for A Hogwarts Express Adventure will begin April 28, with prices starting at $77 for adults and $67 for children ages 2 to 11, depending on departure time.
