Which modern and entertaining film depicts the true story?
None that I know of. However, there are far too many historical errors for the film to be anything but offensive to history buffs.
The whole liason with princess Isabella? Please, she married Edward II years after Wallace had died, and was a small child in France during the time of the movie.
Where are Wallace’s brothers who played no small role in real life?
There was no prima nocta. Never happened. Longshanks might be known as the Hammer of the Scots, but even he didn’t go that far.
The Battle of Stirling Bridge was won by the smaller force exploiting a bottleneck in the same manner the Spartans held the pass of Thermopylae. They did not hold off the English heavy cavalry in an open field with big pointy sticks.
Hell, I take issue with the title. Robert the Bruce is known to the Scots as Braveheart (translation) not William Wallace.
Last but not least, historically, there was a lot of begging during Wallace’s execution, but no heroic cry of “freedom”.
