The theme, officially titled 'He's a Pirate', comes from Pirates of the Caribbean: The Curse of the Black Pearl (2003). It was composed by Klaus Badelt, with Hans Zimmer producing the score, and it plays over Jack Sparrow's most defiant moments. The driving rhythm made it one of the most recognisable film themes of the 2000s, spreading far beyond cinemas into sports arena walkouts, video game montages and countless memes where an ordinary clip suddenly turns epic. Its popularity has never faded because the melody is instantly understood as a signal for bold action.
