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.
The heroic dwarf Thorin in the "Hobbit" trilogy got an early taste of a big-budget fantasy franchise when the then-unknown actor played a Naboo fighter pilot in "The Phantom Menace".
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".
Richard Marquand directed "Return of the Jedi" and also hopped in front of the camera to command one of the Imperial scout walkers -- until he was beaten up by Ewoks.
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.
Every Star Wars fan knows the name Ralph McQuarrie, the man whose artwork defined the iconic visuals of the saga. And you can spot him among the rebel officers on Hoth in "The Empire Strikes Back".
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.
Ralph Brown played the pilot of the shiny spaceship in "The Phantom Menace", but you may remember him as the frazzled drug dealer and roadie from "Withnail and I" and "Wayne's World 2".
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.
Remember that '90s song "I've Got a Little Something For You", by MN8? Sticking with the numbered names, rapper Dee Tails from the band is an L-1 droid in "Rogue One".
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".
"Looper" director Rian Johnson is in charge of "Episode VIII: The Last Jedi", but in a "Rogue One" cameo he was in charge of some Imperial gadgetry as a random technician.
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.
