Finn was introduced in Star Wars: The Force Awakens and gave a whole new perspective of the franchise as a defected stormtrooper. Before embracing his name and joining the Resistance, of course, Finn had a stormtrooper number, which, as it turns out, is an Easter egg that goes all the way to the beginning of the franchise.
Disney recently shared some Easter eggs from different films under the House of Mouse, including Star Wars. Its official Twitter account revealed that Finn's stormtrooper number FN-2187 was an homage to cell 2187 on the Death Star, which was Princess Leia's cell in A New Hope. 2187 is a reference to 21-87 which is a short film at the National Film Board of Canada that inspired George Lucas. You can check out the tweet below.
For those who are curious, 21-87 was a 9-minute and 33-second short film directed by Arthur Lipsett. Released in 1963, the film wasn't actually a space opera, but it was a huge inspiration for the Star Wars creator.
Though the sequel trilogy did reveal some parts of Finn's past, the movies didn't get to fully explore the character's history. That said, Stormtroopers are characters that are typically in the background, so when Finn was introduced back in 2015 with a prominent role, it was a shocking and interesting point in the franchise.
Star Wars: The Rise of Skywalker is available now on 4K Ultra HD, Blu-ray, DVD, and Digital HD.
