Corrected entry: In the movie, it seems like king Edward dies at the same time as Wallace. In reality, Edward I died in 1307, two years after Wallace.
Corrected entry: In the very first fight, Gibson had a flail and antlers. After he hits the 1st guy, he falls from his horse with flail in hand. When attacked by the 2nd guy, a sword is now in his hand and he blocks an attack with it.
