Guest Mathieu,

You're spot on. Straight from the script for the screenplay. It was indeed "MacAulish" that Campbell started shouting, with the crowd of Scotsmen joining in, shouting, "MacAulish! Macaulish! Wallace! Wallace!". But it sounded to me like they were saying, "Mac-Cue-lich." I have been unable to find any evidence that a surname such as MacAulish ever existed. I did come across one historical based website that implied that "MacCulloch" was used as a war cry. I'm not sure how MacAulish or MacCulloch would have been pronounced in those days (or even now, for that matter).      

Cheers,

SND
