 During the film scene at Eilean Donan castle, the car park by the  castle had to be covered up with tons of peat to disguise it, the  house located by the bridge out to the Castle was boxed in with  hardboard and painted over so that it looked just like real stone  even when you stood right beside it. Extras were paid £25 a day with  a £10 bonus if they took their own horse. A lot of the locals took  days off work to do it.
