Next week, the curtain rises on Harry Potter and the Cursed Child's first preview in the West End—and to celebrate, Pottermore has released new portraits of the actors playing Harry, Ginny, and Albus Severus in character.

Cursed Child is a two-part sequel to J.K. Rowling’s book series that, according to its official plot synopsis, follows Harry as “an overworked employee of the Ministry of Magic, a husband and father of three school-age children” who is grappling “with a past that refuses to stay where it belongs.” Meanwhile, Albus Severus, the Potters’ youngest son, “must struggle with the weight of a family legacy he never wanted. As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes, darkness comes from unexpected places.”

Jamie Parker (The History Boys) plays Harry; Poppy Miller (The Second Best Exotic Marigold Hotel) plays Ginny; and Sam Clemmett (Foyle’s War) plays Albus Severus. In the photos posted on Pottermore, the actors wear costumes by Katrina Lindsay and makeup by Carole Hancock.

Parker—who, in addition to those glasses and that lightning-shaped scar, wears a suit to play Ministry employee Harry—told Pottermore that “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.”

Clemmett, meanwhile, is donning those iconic Hogwarts robes—and he had a bit of a backstory for them. “I had the idea he was wearing James’s—his older brother’s—hand-me-downs,” he said. “So I wanted him to feel quite uncomfortable, and be able to play with his clothes.”

Head over to Pottermore to see more photos of the Cursed Child cast in costume and to learn more about their looks (the site will continue to post photos of the other castmembers—there are 42 total—this week). Cursed Child officially opens in the West End on July 30; if you can’t make it to London to see the show, you can pre-order a hardcover copy of the script here.
