Check out the latest Dork Tower comic. Seems a bit like the ending of "Centurion" to me, except that this guy did safely make it back to Hadrian's Wall.
I guess it's a bit of a goof on those wargamers who can't use a figure if it has the wrong cuff colors or bow case covers. And those history enthusiasts who can't have fun at a movie unless everything is historically accurate. This one gave me a good laugh, and I just had to share.
