The kid who landed the lead role in HBO's Harry Potter series walked into his Glasgow audition with a poem he'd written himself — not a scene from the books. David and Becca break down the full casting story behind Finding Harry: The Craft Behind the Magic, HBO's behind-the-scenes special that hit number one on HBO Max worldwide on April 5, beating out actual films despite running just 26 minutes.

They also get into production designer Mara LePere-Schloop's 'rooted in naturalism' philosophy and whether specific choices — British wool, organic cotton, physically connected sets at Leavesden — back it up or amount to polished marketing copy. The creature department's commitment level gets its own conversation, anchored by the detail that each of the ten owls required 36,000 individual feathers, and a biting Scabbers animatronic that points directly to a Philosopher's Stone scene the 2001 film cut entirely.

Costume designer Holly Waddington's fabric logic closes the episode: synthetic clothes for Muggles, natural materials for wizards, with Harry's oversized Dudley hand-me-downs placing him visually between both worlds before he knows he belongs to either. The debate over whether that contrast will actually read on screen when HBO Harry Potter Season 1 drops at Christmas is worth staying for.
