Knightley's role wasn't a big one, but it was a pivotal one. In the end credits, however, her first name is misspelled. Instead of Keira we get Kiera. It's an unusual name, sure, but there is no way to justify it being incorrect in the credits. I may not be as wise as old Obi-Wan Kenobi, but I have a few theories as to why this error exists:
- It was Knightley's first role in a Hollywood blockbuster and came four years before she'd gain worldwide fame as Elizabeth Swann in the Pirates of the Caribbean franchise, so the spelling blunder went unnoticed.
- It's not an error. Keira Knightley has a secret twin sister named Kiera, and it was the latter who played Sabé.
- The person who wrote the end credits was simply following the "i before e except after c" rule.
- One of George Lucas' CGI editing sessions got out of hand, and the closing credits suffered collateral damage.
- Jar Jar Binks did it.
