It's surprising how much wool chainmail still makes it into movies - I think my ultimate scene has to be in Robin and Marion where Sean Connery and Robert Shaw knacker themselves out in about three and ahlaf minutes because they're wearing the real stuff and slogging bloody great swords. Now Robin Hood ... there was a bushman, green tights and all!
My wife and I were in a shop selling armour in Canterbury some years ago (the shop's now gone). She saw a chain mail tunic on a hanger and tried to lift it off the rail, like she would a dress. She couldn't lift it a millimeter it was so heavy!
