Audio problem: King Arthur meets Merlin atop Camelot and he says, "It's a time for men" but his lips say something different. (01:25:10)
Visible crew/equipment: Arthur has just pulled Excalibur out of the stone and he goes running through the woods chasing after Merlin. When he finds him there's a close-up of Merlin and you can see the crew in his shiny silver helmet. (00:31:40)
Audio problem: When they speak for the first time, Morgana says to Merlin, "The essence of it can prolong the act of love" but her lips do not match what she is saying. (01:01:40)
Continuity mistake: As they speak for the first time, Morgana is in the sunlight when she holds the mandrake root in front of Merlin's face. In the next shot when he says, "And if too much is taken?" she's not. (01:01:40)
Continuity mistake: Merlin tries to catch a fish in the stream while King Arthur asks, "Who is this knight?". If you look up at Lancelot's tent his blue and white flag flies to the right then to the left and back again between shots. (00:46:35)
Continuity mistake: When we first see Lancelot in a close-up sitting on his horse next to his tent there are no jousting sticks anywhere to be seen. Later when King Arthur comes across the bridge we see the tent again and there are many jousting sticks around it and near the flag. (00:46:35 - 00:48:00)
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.
