"Brave Heart" is a film adapted from real life. The character prototype of the film is the legendary hero in British history: William Wallace. The script of "Brave Heart" is adapted from the novel published by Randall Wallace in 1995, and the novel is created and reprocessed based on "Song of Wallace". When writing the script, the screenwriter Randall had very little historical data about William Wallace, so Randall created the plot based on the epic recited by the Irish travel poet Henry at the end of the 15th century.
Randall originally planned to write from William Wallace’s adulthood. The preface to joining as a child was a later idea; according to the first draft of the script, Murron was originally given to Wallace at the funeral of Wallace’s father. It was a rose instead of the thistle flower shown in the film, but later someone pointed out that the rose is a symbol of Britain and it was very inappropriate to put it in this drama with a specific historical background, so it was later replaced with thistle flower.
