Actally lynn, she was!
Us Scots are a hardy bunch, and used to go into battle almost naked, but painted with natural dyes and pigments, like camouflage. Hadrian's wall was built to protect the poor Romans from us, and King Arthur is generally believed to have had Celt blood.
I thought the movie was fascinating in how it explained all the legends, like Arthur making an entire enemy army disappear, without use of Merlin's so called magic, but showed how the stories could actually have been done.
Troy which we watched the same night, also seemed to be rewriting myth and legend into a more believable modern analysis.
