This is actually kind of a neat idea. You all know Merlin: Old dude. Big, gray beard. Unimaginable magical powers. Friend to King Arthur and in many ways the proto-wizard from which all other wizened, old spell-flingers were spawned. There are some potentially great stories to be told about Merlin.
One of those is The Lost Years of Merlin, a young-adult novel by T.A. Barron that runs through the great wizard's early years. Paramount had an adaptation set up at one point with Donald De Line producing and Simon Kinberg writing, but those rights lapsed. Now, Warner Bros. has swooped in to give it a shot, The Hollywood Reporter reveals. De Line will stay on as producer while Ed Whitworth, a former script reader for Oprah Winfrey's Harpo Poductions, among others, handles the script. I haven't read the book myself, but this sounds like a potentially fun idea. Hopefully Whitworth is the right guy for the gig.
Fortuitous timing for the WB, too, since next month's final big-screen Harry Potter chapter brings the studio's work on J.K. Rowling's magical world to an end.
