In the 40 years since it began, Star Wars has made household names of stars like Harrison Ford, Mark Hamill and Carrie Fisher. But hidden farther down the saga's cast list is a galaxy of stars you may not have noticed.
From newcomers who weren't famous yet to celebrity cameos to effects wizards stepping in front of the camera, these are quite a few well-known names.
For starters, Simon Pegg made an appearance. To find out which film and which role, check out slide 18.
Little known fact: in one of the more instantly recognisable bit parts in the Star Wars saga, John Ratzenberger played rebel officer Major Derlin -- two years before landing his signature role as Cliff in "Cheers".
Tony Cox, the foul-mouthed elf from "Bad Santa", donned a fur suit for "Return of the Jedi" and two Ewok TV movies. He also has the dubious distinction of appearing in both the Star Wars saga and the Star Wars spoof "Spaceballs".
It's not a trap -- the man who played Admiral Ackbar in both the original movies and "The Force Awakens" was a puppeteer who also operated Sy Snootles and Jabba the Hutt's cackling pet Salacious Crumb. Among his other work, he brought Howard the Duck to life in the disastrous 1986 Marvel comic adaptation, not to mention Cosmo and Dibbs in British kids' show "You And Me".
Animation pioneer Phil Tippett (right), one of the visual effects maestros behind Star Wars, "Indiana Jones" and "Jurassic Park", stood in as an alien in Mos Eisley in "Star Wars", as well as operating the Rancor puppet (pictured) in "Return of the Jedi".
If you need a British bad guy, Julian Glover's your man. As well as leading the AT-AT assault playing General Veers in "The Empire Strikes Back", Glover troubled both James Bond and Indiana Jones before turning up in "Game of Thrones" as Grand Maester Pycelle.
Queen Amidala's entourage includes Saché, played by none other than the director of "The Virgin Suicides" and "Lost in Translation". Sofia Coppola visited the set to hang out with family friend George Lucas. Her brother Roman is also knocking around the senate as a guard.
Model-maker Grant McCune was part of the Oscar-winning visual effects team on Star Wars, as well as working on "Jaws", "Star Trek: The Motion Picture" and many more. He appeared in "A New Hope" as a Death Star Gunner.
Legendary British TV hard man Don Henderson was known for playing detective George Bulman in three series, as well as snarling his way through cult sci-fi shows "Doctor Who" and "Red Dwarf". He played General Tagge in the conference scene in "A New Hope".
In addition to being strangled over Skype in "The Empire Strikes Back", Michael Sheard was feared by a generation of British kids as the tyrannical teacher Mr Bronson in "Grange Hill". He also appeared in "Doctor Who" no less than six times, while US viewers may remember him as Adolf Hitler in "Indiana Jones and the Last Crusade".
Hiss-worthy BBC soap opera villain "Nasty Nick" Cotton from "EastEnders" was part of the rebellion in "Return of the Jedi". Another "EastEnders" villain can be glimpsed in "The Phantom Menace", when Steve John Shepherd -- aka Michael Moon -- appeared on Naboo.
Benjamin Burtt created the immediately recognizable sounds of the Star Wars saga -- the buzz of the lightsabers, Chewbacca's animal roar and more -- and earned an Oscar in the process. He also appeared on screen as the officer who instructs Han Solo to "freeze!" in the Endor shield bunker. In a saga full of lightsabers, lasers and other cool futuristic weapons, Burtt's character is dispatched by a toolbox.
From "Absolutely Fabulous" and various roles alongside the late comedienne Victoria Wood, Celia Imrie (centre) improbably climbed into a spacefighter cockpit in "The Phantom Menace". The trend for distinguished British actresses flying spaceships continued in "Rogue One", in which Geraldine James (left) was Blue Three.
John Knoll is the Oscar-winning visual effects supervisor on various Star Trek, Star Wars and Pirates of the Caribbean movies. After jumping into the cockpit of a Naboo fighter in "Phantom Menace", he had the idea to make a film about the Death Star plans -- which became "Rogue One". Oh, and he also straight-up invented Photoshop.
Liam Neeson (left) doesn't have much form at handing out advice to boys in his charge: first Anakin Skywalker turned to the Dark Side, and then Thomas Brodie-Sangster, his son from "Love Actually", winds up as an Imperial officer in "The Force Awakens".
Fans of classic "Doctor Who" will remember Richard Franklin (left) as the dashing Captain Mike Yates, a series regular alongside Jon Pertwee's third Doctor in the 1970s. He appeared as an engineer in "Rogue One".
Under the helmet of "Force Awakens" Stormtrooper FN-9330 is music producer Nigel Godrich (centre, performing with Thom Yorke), who's overseen every Radiohead album since the 1990s. He's joined under Stormtrooper helmet FN-3181 by movie composer Michael Giacchino, who has written music for Star Trek and Star Wars.
