Traditionally, Robin Hood movies consist of men in tights and/ or armour firing arrows at each other through trees. But when Kevin Costner is involved, things get blown up. Even if dynamite wasn't invented for another 600 years.
In Prince Of Thieves, it's Robin's best mate, Azeem, who comes up with the plan to plant what appears to be gunpowder around the Sheriff's castle. When things get a bit tasty, Azeem lets rip with a flaming arrow, much to the surprise of everyone in the castle who, presumably, had never seen an explosion before.
