HBOHBO’s ambitious ‘Harry Potter’ adaptation has been steadily assembling one of the most closely watched casts in television, dedicating each season to a single book from J.K. Rowling’s beloved series. With Season 1’s “Harry Potter and the Philosopher’s Stone” set to premiere on December 25 and the show already renewed for a second season adapting “Harry Potter and the Chamber of Secrets,” fans have spent months speculating about which actors might join the sprawling wizarding world. Deadline has now confirmed exactly who’s taking on that challenge, revealing that Nicholas Hoult has joined Season 2 of HBO’s ‘Harry Potter’ series as Gilderoy Lockhart. As a child, he actually auditioned to play Harry Potter himself, ultimately losing the role to Daniel Radcliffe before the original film series ever began. How do you feel about Nicholas Hoult joining HBO’s Harry Potter as Gilderoy Lockhart?
