HBO has released the first look at the comedian and actor in costume as the half-giant and Hogwarts groundskeeper Rubeus Hagrid for its upcoming "Harry Potter" series.

The studio where the new Harry Potter television reboot will be filmed has been granted permission to build a temporary school.

The casting of the three main roles (Harry, Hermonie and Ron) followed an open casting call, announced last year, that saw more than 30,000 children audition for the coveted parts.
