A fun fact about the "Pirates of the Caribbean" film series is that Johnny Depp's portrayal of Captain Jack Sparrow was initially met with skepticism by Disney executives. Depp's eccentric and unconventional interpretation of the character, including the quirky mannerisms and unique speech pattern, was quite different from what the executives had envisioned.

However, Depp's performance went on to become one of the most iconic aspects of the franchise, earning him widespread acclaim and even an Academy Award nomination for Best Actor for his role in the first film, "Pirates of the Caribbean: The Curse of the Black Pearl" (2003). Captain Jack Sparrow became a beloved and memorable character, and Depp's portrayal significantly contributed to the success and popularity of the entire Pirates of the Caribbean series.
