The first ever flicks from the set of the upcoming Harry Potter TV series on HBO Max feature the cast arriving at the London Zoo to shoot the memorable Dudley Dursley birthday scene from the very first book and film, and fans are losing their minds over one key detail.

The first look at the Shaun of the Dead actor as Rubeus Hagrid in the upcoming HBO series has been revealed, and he's almost unrecognizable in the photo of him as the lovable half-giant.

Several high-profile actors have been announced in other key roles, including Paapa Essiedu as Severus Snape, John Lithgow as Albus Dumbledore and Katherine Parkinson as Molly Weasley.
