The highly anticipated 'Harry Potter' series now has a major update, with possibly another big one in the offing. HBO Max revealed the first look at Dominic McLaughlin's young Harry in its latest Instagram post. The network also teased that the first trailer might be released on Wednesday, captioning the picture 'Tomorrow' and adding the iconic lightning bolt emoji. The image depicts the wizard approaching the Quidditch pitch in a Gryffindor cloak on a snowy day.

The series will reimagine author J.K. Rowling’s seven fantasy novels. The project is the latest in a series of eight movie adaptations that have collectively grossed over $7 billion. Each season covers one book with 'Succession' fame's Francesca Gardiner tapped as showrunner. 'Game of Thrones' veteran Mark Mylod is directing several episodes of the show. On the cast front, McLaughlin stars as the titular wizard alongside Alastair Stout as Harry’s best friend Ron Weasley, and Arabella Stanton as Hermione Granger. Nick Frost as Rubeus Hagrid, John Lithgow as Albus Dumbledore, and Janet McTeer as Professor McGonagall round up the major names.
