Every part of Star Wars: The Force Awakens was carefully crafted to call back to the series' long running history. Even the voices of many of the creatures and soldiers with just one line often have long history with the series.

In a post to the official Star Wars website, supervising sound editor Matthew Wood detailed many, though not all of the sources of the voices heard in the film.

Actors from Star Wars Rebels and Star Wars: The Clone Wars TV shows (Dee Bradley Baker, Catherine Taber, and Tom Kane) and from Star Wars Battlefront (David Collins) made appearances. Everyone's favorite Stormtrooper, known among fans at TR-8R, in honor of his line, "Traitor!" was voiced by Skywalker Sound's David Acord, a long time member of the studio. Sam Witwer, the voice and face of Starkiller in the Force Unleashed games, had a few lines as well.

Director Kevin Smith and Radiohead producer Nigel Godrich had lines as well. One weird line toward the beginning, uttered by the "Red-Eyed Sand Alien" and voiced by sound designer Robert Stambler, turned out to be "Kojima," referencing the director of the Metal Gear video games.

As Polygon notes, Kojima had hung out with director J.J. Abrams at least once or twice.

Wood didn't call out the Daniel Craig cameo that many believe takes place when Rey is escaping from Kylo Ren and his torture chair, and there may be other cameos as well, but it's cool to see so much of the property's history being incorporated, even in small ways.
