The lasting Harry Potter casting news

Severus Snape - Paapa Essiedu

Known for his roles in I May Destroy You and The Lazarus Project, it was recently reported that Paapa was a top contender for the role of Hogwarts' Potion's master, Snape. The character is best known to be one of Harry's key adversaries, making the Boy Who Lived's time at Hogwarts a nightmare while having mysterious motives behind his profound dislike for poor old Harry. 

With Paapa's incredible background with the Royal Shakespeare Company, we think he could be a worthy successor for the late, great Sir Alan Rickman, who originated the iconic role.

Aunt Petunia - Bel Powley

Fiona Shaw originated the role of Harry's highly strung, slightly hysterical aunt who overindulges in cousin Dudley, but Bel will be the next star to take on the role, and we think she'll do it in her stride!

It would be a very different take - but we can see the A Small Light star whipping up a meringue layer cake at number 4 Privet Drive.

Albus Dumbledore - John Lithgow

Unlike the original movie series, where the casting was strictly Brits only, it seems that HBO are taking a different tact as the US born star will play Hogwarts' twinkly eyed headmaster. 

John has wowed before in his roles of Winston Churchill in The Crown, and recently portrayed Roald Dahl in The Royal Court's Giant - and so we know he has the accent perfected!

Janet McTeer - Professor McGonagall

Kaos star Janet McTeer will play the Scottish deputy headmistress of Hogwarts - and the head of Gryffindor house - Minerva McGonagall. And honestly? She couldn't be more perfect for the role. 

Who else would be able to portray a completely biased love of Quidditch and tell Harry off for not taking a ginger newt biscuit? Sign us up!

Nick Frost - Rubeus Hagrid

It's official. Hot Fuzz and Shaun of the Dead star Nick Frost has been cast as the hairy, half-giant groundskeeper of Hogwarts, Rebeus Hagrid. 

Following in the footsteps of the late Robbie Coltrane, the role would see Brett befriend Harry, Ron and Hermione while accidentally landed them in sticky situations.

Paul Whitehead

The delightful Paul Whitehead, best known for his roles in The Death of Stalin, Alice in Wonderland and Corpse Bride, is confirmed to play Hogwarts' grouchy caretaker, Argus Filch, in the upcoming series.

Filch is a miserable sort who is hellbent on catching youngsters out of bounds and sending them packing from Hogwarts, and we think Paul will have a lot of fun in the role!

Luke Thallon - Professor Quirrell

Luke, who previously appeared in The Favourite, is set to play Quirrell in the HBO series. 

Professor Quirrell is Harry and his friends' Defence Against the Dark Arts teacher at Hogwarts, but his travels have left him with frayed nerves and a stammer. He is a key role in the first novel, Harry Potter and the Philosopher's Stone.
