Djimon Hounsou is in talks for the role of King Arthur’s mentor in Warner Bros. and Village Roadshow’s “Knights of the Round Table.”

Guy Ritchie is directing with Charlie Hunnam playing Arthur and Astrid Berges-Frisbey playing Guinevere. Jude Law is also in talks for the role of the villain.

Idris Elba was also up for the role, but when dates could not be figured out, the studio turned to Hounsou for the role described as a Merlin-esque figure who trains and mentors Arthur.

Joby Harold wrote the the script and is producing with Ritchie, Lionel Wigram, Akiva Goldsman and Tory Tunnell. Plot details are being kept under wraps, and the pic will open on July 22, 2016. Niija Kuykendall and Cate Adams are overseeing for the studio.

The studio hopes the film can kickstart another franchise for Warner Bros., with the story to be told over six installments.

Hounsou has been busy lining up roles in several franchises in the past year. He can be seen next in Universal’s “The Fast and Furious 7” which bows next April and also has a supporting role in Warner Bros. “Tarzan” set to bow in July 2016. He also appeared in this summer’s “Guardians of the Galaxy.”

He also has Legendary’s “Seventh Son” debuting next year. He is repped by CAA and the Safran Group.
