Kevin McKidd was particularly happy to work on this project because it was the first time in years that he'd been able to use his natural Scottish accent in a movie.
Two additional software programs were specially developed for this movie by Pixar in a span of three years. One of them allowed simulation of Merida's one thousand five hundred strands of hair curls to move together with her movements.
The misunderstood dialect that Young MacGuffin (Kevin McKidd) speaks is called Doric. It is spoken in northeastern Scotland, including Kevin McKidd's hometown of Elgin.
There was a scene storyboarded where Merida was actually interested in Young MacGuffin, but the scene was scrapped because they wanted to focus on the love between a mother and daughter.
