Went to see the new movie 'War Horse' with my wife and daughter last night. The movie proved to be rather maudlin and melodramatic but the scenes done of WWI were actually pretty good. (My grandfather served in the war in Europe with the British Army so I had more than a passing interest in the uniforms, weapons etc.)

There was a brief scene with a piper as they "went over the top" but he was in khaki.

The only kilt I saw was in a scene toward the end just as the horse was led into an auction paddock after the armistice. It was fleeting but looked to be dark green/navy but I couldn't identify.
