Star Wars is full of interesting and lively characters, both good and evil, but not all of them are equal in of the amount of dialogue they deliver. As with most movies, it can be hard to prioritize a bunch of characters in one setting, which means some are destined to remain as bit players in the background.
However, Star Wars is a bit different. Even very popular characters sometimes get stiffed when it comes to the script, which means they have very few actual lines in the films. Sometimes this is a good thing, as it can help sell the mystery of the character or give them a more powerful screen presence. Other times, it's an unfortunate oversight.
Chewbacca
Chewbacca is very, very vocal, but little of what he says translates into actual words. Most of the time, he's busy screaming and yelling in frustration, which means he has far fewer lines than many Star Wars fans think. Much of Chewbacca's performance relies heavily on his body language and sense of physical timing.
Since the audience can't understand Wookiee and there are no subtitles to assist, it's up to other characters to give some insight into what he's saying, which is rare. Chewbacca is a character that is quick to action, and he doesn't waste a lot of time on words.
Crix Madine
General Crix Madine has an interesting backstory, both in the canonical Star Wars timeline as well as the Expanded Universe (Legends) material. He's only around for one short scene in Return of the Jedi where he discusses the plan to insert a strike team on Endor to knock out the Death Star's shield generator.
Several other shots of Madine never made it into the final cut of Return of the Jedi, and his character was only expanded on in ancillary material. It's a shame, because Madine's history with the Empire combined with his knowledge of covert ops tactics makes him far interesting than just one scene with a few lines of dialogue.
Dak Ralter
The idealistic young Dak Ralter served as the gunner for Luke Skywalker inside his Snowspeeder, and was present during the battle of Hoth. When the Imperials launched a ground assault, the two participated in the mission to bring down the AT-AT Walkers, only to discover that they were largely invulnerable to blaster fire.
Before Skywalker could implement his own plan to trip up the Walkers with a tow cable, their Snowspeeder was hit, and Dak was killed. He only spoke a few lines in the film before meeting his unfortunate end.
Ki-Adi-Mundi
Though a prominent member of the Jedi Council, Ki-Adi-Mundi got a remarkably low amount of screen time in the Star Wars prequel trilogy. He had only a few lines to his name before his character was killed in Revenge of Sith.
Thankfully, Mundi would get more lines in the Clone Wars animated series, but the film version of the character was mostly kept around to give extra exposition. For instance, he was the first Jedi to accurately determine that young Anakin Skywalker missed his mother, and noted the fear that sprang from that loss.
Darth Maul
This terrifying character had the least lines of any Sith Lord in the Star Wars films, bar none. Darth Maul would get a second shot at life in the Clone Wars and Rebels animated series, but his presence in The Phantom Menace was clearly meant to sell the terror of the Sith.
He only speaks a handful of very short lines in the film, none of which occur during Darth Maul's iconic fight with Obi-Wan and Qui-Gon. This was perhaps done on purpose, to conceal the nature of the Sith's involvement with galactic affairs while simultaneously sowing the seeds of doubt within the Jedi Order.
Boba Fett
Boba Fett's strong and silent personality probably contributed to the popularity of his character. As such, he said very little throughout the course of the films. Originally introduced as a young, unaltered clone of Jango Fett in Attack of the Clones, he'd later grow up to become the galaxy's most feared bounty hunter.
Only when season 2 of The Mandalorian dropped on Disney+ did audiences actually see a more verbose version of the character. In the films, he mutters only a few lines before suffering an unfortunate turn of events in Return of the Jedi. He's undoubtedly going to have a lot more to say in the Book of Boba Fett series.
General Jan Dodonna
He might be considered something of a throwaway character in Star Wars, but General Jan Dodonna is a really interesting character. He got a bit part in the final act of the original Star Wars where he discussed the Death Star schematics and the plan to attack the battle station over Yavin 4.
Dodonna made a reappearance in Rogue One, this time played by a different actor, but he didn't have much to say in that film either. He was one of the Rebellion's most influential and highest-ranking , but it's hard to tell, given how little he says.
Biggs Darklighter
Luke Skywalker's childhood buddy Biggs Darklighter managed to make it off-world long before he did, and ed the Rebellion as an X-Wing pilot. In the theatrical cut of the film, Biggs barely gets any screen time, but the Special Edition gave him a bit more exposure.
His only real claim to fame is a deleted scene added back into the movie where he meets Luke Skywalker in the launch bay on Yavin 4. They manage to catch up a little bit shortly before the attack on the Death Star, where Biggs met his unfortunate end.
Aunt Beru
Aunt Beru and Uncle Owen were only around for a short time in the first Star Wars film before they were both killed by the Empire's stormtroopers. However, Owen got way more lines than Beru did, who spent most of her time smiling and nodding.
Beru only has one real moment to her credit, which takes place when Luke Skywalker storms off in frustration after he learns he'll have to stick around on Tatooine for another year. The character should get another shot in the Obi-Wan series on Disney+, but it remains to be seen in what capacity.
Lobot
Lando Calrissian's aide Lobot was instrumental in helping him run Cloud City, thanks to his cybernetic implants. The character was considered one of Lando's closest friends, though a terrible accident caused his human mind to be wiped, at which point his cybernetics took over.
Lobot doesn't say anything at all in The Empire Strikes Back, and he's there mostly to establish the fact that Lando had a backup plan in effect in case things went pear-shaped. All of his "lines" are delivered largely through body language, as opposed to speaking aloud.
