I was an extra on the Highlander Scottish battle scenes and since Scottish weather isn't the most hospitable, all the extras got very drunk on whisky to keep warm. When you see the Scottish charge insanely, it's because we were all drunk, which led to us picking out the wrong weapons and kilts for the next days filming because no one could remember who had what.

In the video versions, the scene where MacLeod rescues Rachel, the text the German SS officer speaks has not been subtitled or otherwise translated, so it may not be obvious why MacLeod eventually kills the German (I don't know whether that was rectified in the DVDs). Here the translation of the German text: MacLeod trips up the officer and seizes his weapon. The German calls: "You should be dead." When MacLeod orders him to move, the German says: "No. First you will have to shoot me." Then MacLeod gives off his opinion about the 'master race', and then shoots him.
