Well, I wouldn't swear an oath that this is the worst movie ever made, but dishonourable mention, at the very least, has to go to Knights of the Round Table with Robert Taylor as Lancelot. The fight scenes could have been staged by a bunch of Society of Creative Anachronism drop outs. The scene where Arthur confronts a bunch of nasty warlords, including the King of the Picts, at Stonehenge is just priceless.
