The Kid Who Would Be King is an upcoming film that will be released on March 01, 2019. It's yet another take on the Arthurian legend. Personally, I've grown weary of Camelot-related adaptations. I think Hollywood should give it a rest for a while.
What excites me about this movie is it's the first film Joe Cornish has directed since Attack the Block, released in 2011. I really liked that one, so hopefully this is another good one.
