Kit Harington Cast as Gilderoy Lockhart in HBO's Harry Potter TV Series

Kit Harington will play Gilderoy Lockhart in HBO's Harry Potter TV series, replacing Nicholas Hoult due to scheduling conflicts. Season 2 will adapt The Chamber of Secrets, with a cast including Dominic McLaughlin, Alastair Stout, Arabella Stanton, Jon Lithgow, and Nick Frost; the show is planned as a multi-season adaptation spanning Rowling's seven books, potentially taking about a decade to complete. Harington has previously voiced Lockhart in an Audible edition and has prior HBO collaborations.
