There’s a little magic happening on the London stage. On Pottermore, J.K. Rowling unveiled the first photos of “Harry Potter and theCursed Child’s” main cast, including Jamie Parker as Harry Potter, Poppy Miller as his wife Ginny and Sam Clemmett as their son Albus Severus Potter.

As to Harry’s new look, Parker said, “With all the character’s costumes we want them to be instantly familiar when people see them, so that people feel like the story’s safe in our hands, and that we’re taking that responsibility seriously.’”

“It’s a unique gig in the sense that you have seven volumes of backstory that you get to bring on with you. And we were all very keen to make sure that the first time you see Harry it just feels right,” he added.

Of Miller, Rowling shared, “I think a lot of people would like to have Poppy’s Ginny for a mother. Kind and cool, exactly as I imagined her.”

“There’s much I could say about Sam-as-Albus, but we’d be into spoiler territory so quickly I’ll just say we couldn’t have cast better,” she added.

Written by Rowling and Jack Thorne, “Cursed Child” picks up just after the epilogue of “Harry Potter and the Deathly Hallows,” where an adult Harry waves off his children at Platform Nine and Three-Quarters.

“Harry Potter and the Cursed Child” opens July 30 at the Palace Theater in London.
