Guy Ritchie’s King Arthur looks to have found its leading man, with Deadline reporting that Charlie Hunnam is in final negotiations to join the production.

Hunnam will play the titular monarch, and will join Idris Elba, who has already been cast as his mentor in a role similar to (although not explicitly described as) that of Merlin.

Meanwhile, Variety is also reporting that Elizabeth Olsen is the frontrunner to play the female lead, who we would assume to be Guinevere, Arthur’s queen.

With a script having been penned by screenwriter Joby Harrold, it has been suggested that the first film will introduce a series of six big-screen adventures, although clearly that will depend on the success of the initial outing.

Directed by Ritchie, King Arthur will open in the UK on 22 July 2016.
