It had originally been intended to film in other locations but the Department of the Environment, which at the time looked after all castles in state care, withdrew it's permission to use it's castles two weeks before filming was due to start. Doune Castle at the time was privately owned so could be used for filming. Doune Castle is now run by Scottish Heritage the sucessor several times removed to the Department of the Envirionment. Ironically, a lot of the visitors to the castle now go there purely because of the movie connection. Apparently, a Monty Python appearance is how to get more views on youtube and how to get more visitors to your castle. Outside filming locations were down the small hill to the left of the castle entrance (Castle of Guy de Lombard trojan rabbit), the front gate (Swamp Castle), wall to the left of the gate (swallow scene and french scene) and at the rear of the castle. For the french scenes at the beginning of the movie a fake wall was built at ground level and the camera pointed up the hill at the rear of the castle to give the appearance of height.
