We’ve been waiting seven long years for Joe Cornish’s directorial follow-up to Attack the Block and in that time he helped Edgar Wright pen Ant-Man and developed a few ill-fated projects including an adaptation of Neal Stephenson’s Snow Crash (which now seems to be turning into a TV series). But next year he is bringing us a new take on the King Arthur mythology aimed at a younger audience called The Kid Who Would Be King. Believe it or not, this is an original script from Cornish himself and not based on a YA novel of any sort and the story revolves around a kid who stumbles across the fabled sword Excalibur and is tasked with assembling a new roundtable of young knights. Patrick Stewart plays Merlin and Rebecca Ferguson plays the evil Morgana, need I say more? Truth be told, the first trailer feels a bit generic, but it’s just nice to see a new live-action adventure film for kids as they seem to be pretty rare these days. The Kid Who Would Be King hits theatres on March 1st, 2019; check out the trailer after the jump and see what you think.
