The trailer drop comes one day after HBO shared the first official production still from the first season. The image features Harry Potter, played by McLaughlin, rocking Gryffindor Quidditch robes and walking onto the pitch. The image is from behind, so you can’t see Harry’s face, but he is holding his Nimbus 2000 broom.

A trailer has been released for the much-anticipated new Harry Potter TV series, showing the young wizard with his friends Hermione and Ron as they travel on the Hogwarts Express.

Hermoine is played by Arabella Stanton after a casting call saw about 32,000 children audition for the three lead roles, with the team reviewing up to 1,000 tapes a day.
