Swashbuckler films are a subgenre of the action film genre, characterised by swordfighting and adventurous heroic characters, known as swashbucklers. While morality is typically clear-cut, heroes and villains alike often follow a code of honour. Some swashbuckler films have romantic elements, most frequently a damsel in distress. Both real and fictional historical events often feature prominently in the plot.
