Kit Harington and Keira Knightley join Harry Potter audiobook cast
Harry Potter: The Full-Cast Audio Editions has announced more stars lending their voices to the audiobooks, including Kit Harington, Keira Knightley and James McAvoy.

Kit Harington and Keira Knightley have been cast in the new Harry Potter audiobook series.
The Game of Thrones actor and Black Doves actress are among the 10 new stars lending their voices to the Harry Potter: The Full-Cast Audio Editions.
Kit will voice Professor Lockhart with Keira taking on the role of Professor Umbridge in the upcoming Pottermore Publishing and Audible project.
Game of Thrones' Iwan Rheon and Gemma Whelan will voice Professor Lupin and Professor Sprout respectively, with Ruth Wilson joining as Bellatrix Lestrange, Ambika Mod playing Nymphadora Tonks, and Leo Woodall as Bill Weasley.
James McAvoy has also joined as Mad-Eye Moody, while Matt Berry will voice Sir Cadogan.
For the new audiobooks, Arthur Weasley will be played by Simon Pegg, whose Hot Fuzz co-star Nick Frost is portraying Rubeus Hagrid in HBO's separate TV revival of the wizarding franchise.
Casting for a number of key roles already been confirmed for the audiobooks.
For the first three books - The Philosopher's Stone, Chamber of Secrets and Prisoner of Azkaban - Frankie Treadaway, Max Lester and Arabella Stanton will voice Harry Potter, Ron Weasley and Hermione Granger respectively.
Arabella has also been cast as Hermione in HBO's reboot, alongside Dominic McLaughlin (Harry) and Alastair Stout (Ron).
For the final four audiobooks - Goblet of Fire, Order of the Phoenix, Half-Blood Prince and the Deathly Hallows - Frankie, Max and Lester will be replaced by Jaxon Knopf, Rhys Mulligan and Nina Barker-Francis.
Elsewhere in the Full-Cast Audio Editions, Cush Jumbo will narrate, with Hugh Laurie (Albus Dumbledore), Matthew Macfadyen (Lord Voldemort), Riz Ahmed (Professor Snape), Michelle Gomez (Professor McGonagall) and Mark Addy (Hagrid).
The cast so far is rounded off by Alex Hassell as Lucius Malfoy, Daniel Mays as Dobby, and Sara and Anvi Deshmukh as the Patil twins.
The audiobooks are separate from HBO's series, and Game of Thrones star Sophie Turner recently offered a word of warning for Dominic, Alastair and Arabella about life as a child star.
She told Flaunt magazine: “I look at the kids who are about to be in the new Harry Potter and I just want to give them a hug and say, ‘Look, it’s going to be okay but don’t go anywhere near [social media].
“'Stay friends with your home friends, keep living at home with your family, make sure your parents are your chaperones — it’s so important to have that grounding adjacent to the big, crazy stuff that you do.’”
