Rogue One's Unique Approach to Cameos and Fan Service
Rogue One: A Star Wars Story has laid out the best pattern for incorporating cameos and fan service into Star Wars media. Rogue One is arguably one of Star Wars' best movies to date in terms of both writing and storytelling. It answered two decades-long questions - how Leia acquired the information that led to the destruction of the Death Star, and why the Death Star contained such an obvious design flaw - concisely and believably. It was also unique in how it incorporated cameos and fan service into the narrative, setting a precedent for the stories that followed - including those done by Lucasfilm's Dave Filoni.

In an interview with IGN, Filoni discusses Chopper from his animated series Star Wars Rebels making a brief cameo in Rogue One. He emphasizes the importance of keeping him in the background as opposed to being given a spotlight, as 'the story's not about him.' Not only is it important, but Filoni also believes it's more rewarding to viewers, as it gives them the opportunity to use 'that insider knowledge which they discovered' by making connections to other stories. This helps to keep both the weight of a notable Star Wars cameo and the joy of the audience in balance, with the main focus remaining on the story at hand.
While many well-known characters such as Darth Vader, Saw Gerrera, Grand Moff Tarkin, and Mon Mothma all make appearances in Rogue One, they're not the focus of the movie. Chopper is in the background at one point, but he doesn't have any lines. He's simply shown to be there as far as he would reasonably be expected to. There is no attempt to cram in a line or force an interaction that wouldn't make sense just to remind the audience that this is a Star Wars movie. Instead, Rogue One walks the fine line between showing that the popular characters are present while not allowing them to overshadow the story.
Cameos like this are exciting because they give back to fans. They allow for a deep connection and give die-hard fans the excitement of having insider knowledge. However, too often Star Wars has gone overboard in these moments. Rather than placing popular characters in the background or only incorporating them insofar as it fits the narrative, Star Wars often forces cameos and fan service into their movies and TV shows in awkward ways. This kind of fan service takes the audience out of the moment and reminds them that what they are watching is specifically a Star Wars movie.
Rogue One, however, incorporates prominent characters and familiar ships such as the Ghost in an organic way, so it doesn't feel like just another Star Wars movie. It is still distinctly Star Wars, of course, but it also feels like its own story, following compelling new characters. Thus, Lucasfilm ought to continue to use Rogue One as a template for incorporating cameos and fan service into its future Star Wars projects.
