Nick Frost has said he 'will not let Robbie Coltrane down' after being confirmed as Hagrid in the HBO Harry Potter series.

The English comedian and actor has been announced as one of the many stars appearing in the new HBO Harry Potter TV series.

The 53-year-old is set to play the iconic gameskeeper at Hogwarts, Rubeus Hagrid, who was portrayed by Robbie Coltraine in the film series.

He will be joining the likes of John Lithgow as Hogwarts headmaster Professor Albus Dumbledore and Paapa Essiedu as Professor of Potions, Severus Snape, among others.

In an Instagram post, which he has since been forced to turn the comments off on, he said: "You’re a wizard, Harry!!! Thank you for trusting me with such a loyal, gentle and courageous half-giant like Rubeus Hagrid. Robbie, I promise I won’t let you down."

After the news of Frost's casting, here is everything you need to know about the popular actor, from his hilarious Cornetto trilogy to his extensive television career.
