Harry Potter's reboot casting news so far: Dumbledore, Hagrid, Quirrell and more

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.  

Fiona Shaw originated the role of Harry's highly strung, slightly hysterical aunt who overindulges in cousin Dudley, but we can seriously imagine Phoebe taking the role in her stride and making her hilarious. It would be a very different take - but what can we see, we can see the Fleabag star whipping up a meringue layer cake at number 4 Privet Drive. 

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! 

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!

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. 

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, 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.
