When bandits ambush Guinevere and Lancelot, Guinevere and her horse are pulled down to the ground by two men. After focusing briefly on Lancelot fighting the bandits off, we return to Guinevere and see only one man pulling her away. After another Lancelot shot, there are two men again.

There is a noticeable difference in the location of the tattoo on Viviane's forehead, between where she is telling Igraine the children must be taken away, and when Morgaine and Arthur are separated.

When Vivian and Morgaine (child) are moving through the field on their way to Avalon, Vivian is telling Morgaine about the Lady. Watch the two peasants - they kneel twice.

Accolon and Morgaine can already be seen dancing in the background of the first shot of Lancelot's wedding reception.

Although the time period of Arthur should be the 5th or 6th century, much of the costume, custom, design, weaponry, etc, is from a much later date. The Arthurian legend became widely popular only during the 15th century, when Thomas Malory updated the setting to his own time. Most popular works of Arthurian fiction continue this trend of treating Arthur as a 15th-century king.

When young Morgaine and young Arthur run away on horseback, it is obvious that the next two shots are a stuntwoman on the horse with the young boy in front of her in the saddle.

During the stag hunt, a mesh wire fence is visible behind the stag.

When Morgaine and Lancelot are sitting in the circle of stones together, a device that generates the mist can be clearly seen in the lower right-hand corner.

"Call no man happy until he is dead" is a quote from the Greek philosopher Solon, and not the "old Roman".
