Visible crew/equipment: After Arthur drinks from the Grail and goes to visit Gwinevere at the convent and she gives him the sword back, he paces around her chamber- you can clearly see the film crew reflected in his armor.
Audio problem: When Uther takes the baby from Igrayne and gives it to Merlin, Igrayne's screaming and whimpering is not consistent with her mouth movements.
Other mistake: When Arthur and all his knights assemble on hilltop at night and Merlin tells them all not to forget where the Round Table started, you can see the crew's spotlights reflected on the back of some of the knights' armour.
Continuity mistake: When Arthur is dying after killing Mordred, he drops to his knees with the spear still through him. When Sir Percivle is next to him getting his last instructions, the spear is gone.
Audio problem: In the scene where Arthur meets Lancelot for the first time on the bridge, a car can be heard just after he crosses to Lancelot's side of the bridge.
Other mistake: At the siege of Leondegrance's castle, when they show the knights on top of the siege tower moving to the wall, one knight in particular puts a cigarette in his mouth through the breathing slit in his helmet before crossing onto the wall.
Revealing mistake: In the scene where Sir Percival is attacked by the peasants, the green floodlights that were used by the crew to enhance the colour of the foliage are reflected in the actor's armour and the blonde hair of a peasant girl.
Answer: They were the Goddesses of Avalon. A group of women who each have a specific magical power. They were the makers of Excalibur, healed King Arthur's wounds from his first battle and took him to his final resting place, readying him for the day he would be needed again.
Most Arthurian myths attribute elves as making "Excalibur", and also "Clarent," King Arthur's other magical sword.
