Trivia: The opening crawl makes reference to Palpatine announcing his return from the dead through a broadcast. The film itself doesn't reveal what was said in the broadcast, but it was revealed in a Star Wars Fortnite event. The exact broadcast is as follows: "At last the work of generations is complete. The great error is corrected. The day of victory is at hand. The day of revenge. The day of the Sith."
Trivia: Director JJ Abrams has a vocal cameo as the droid D-0.
