Warner Bros. is set to produce a big-budget adaptation of the first book of the fantasy series by T.A. Barron, The Lost Years of Merlin.

According to The Hollywood Reporter, Donald De Line (Green Lantern) is producing what is basically an origin story of the mythical wizard, Merlin, which will trace his journey from being a boy washed on the shores of Wales with no memory and no home, to him becoming a young man learning to use his powers and ultimately defender of the natural world and eventual mentor to King Arthur.

The project previously had been at Paramount, where Simon Kinberg (Mr. and Mrs. Smith, Sherlock Holmes) was taking a crack at it. But the option ran out and Warners, looking for a suitable replacement for its billion-dollar Harry Potter franchise, picked it up with De Line attached.

Ed Whitworth is now writing the script.
