Hunnam will reunite with Pacific Rim co-star Idris Elba, in the role of the Merlin-esque character who guides Arthur. There is also word that Elizabeth Olson is the front-runner for the female lead. Which would be alright by a lot of us, I imagine.
And while some say, "Strange women lying in ponds distributing swords is no basis for a system of government," we have not had a really good King Arthur flick since 1981's Excalibur.
Warner Bros. plans to release the first film in July 2016.
