This is also due to be released in 2017 and it definitely looks like a movie to see on a really big screen.
The last King Arthur movie I saw was the version based on a theory that King Arthur was a Roman soldier who joined forces with the wild locals who lived in Britain at the time. Clive Owen and Keira Knightley made that movie for me.
This new movie looks like a return to a more classic interpretation of the story complete with magic and fantastic creatures. Not exactly a demystification of the story as the 2004 movie promised but I’m ok with that.
