George Lucas as Baron Papanoida
It's not unusual for creative-types to appear in their own movies but perhaps George's choice of cameo is a little less than conventional. You can find George hanging around outside Palpatine's private box at the Galaxies Opera House in 'Revenge of the Sith' - dressed as the blue-skinned Pantoran statesman, Baron Papanoida. I'll be honest, I've always wondered whether he knew what was going on… or if it was just one big practical joke by the visual effects team.
Brian Blessed as Boss Nass
Known for his large, hearty stature and his even larger voice, Brian Blessed made a rather vocal cameo appearance in 'Episode I: The Phantom Menace'. Taking to the role like a Gungan to water, Blessed's booming baritone is put to great use as the voice of Boss Nass - the loud, brash and thoroughly bombastic Gungan leader. Despite putting on a rather odd voice, you can tell it's Brian almost immediately… and if you listen close enough, you can almost hear him shout 'Gordon's alive?'
Joe Johnston as an Imperial Gunner
Joe Johnston, director of the Avengers spin-off 'Captain America: The First Avenger', briefly appeared in 'Episode IV - A New Hope'. In fact, he played a number of Imperial troopers including an Imperial gunner and Spacetrooper. Not exactly the most impressive of cameos but he more than makes up for it with his pre-production work - having designed the iconic Mandalorian armour and equipment used by Boba Fett.
Keira Knightley as Sabé
A long time ago, in a galaxy before 'Pirates of the Caribbean', Keira Knightley made a cameo appearance as one of Padmé Amidala's handmaidens in the prequel film, 'The Phantom Menace'. Chosen for the role thanks to her resemblance to Natalie Portman, Keira played Queen Amidala's doppelganger and personal bodyguard.
Sofia Coppola as Saché
This budding young screenwriter appeared in 'The Phantom Menace' as one of Padmé Amidala's handmaidens… and spent most of her time on-screen looking wistfully off into the distance. Best known for writing and directing the Bill Murray classic, 'Lost in Translation', she has appeared in several of her father's films including the entire 'Godfather' trilogy. It's not what you know; it's who you know…
Anthony Daniels as Dannl Faytonni
When deciding cameo appearances, the choice for Anthony Daniels was an obvious one - after all, the prim and proper C-3PO would make an excellent con-artist. Appearing in 'Attack of the Clones' as the small-time hustler, Dannl Faytonni, Anthony Daniels couldn't get further from his original role. And starring alongside him as his criminal co-conspirator is none other than Ahmed Best - the voice of Jar Jar Binks. I know what you're thinking… but try not to hold that against him.
Jeremy Bulloch as Jeremoch Colton
Of course, Anthony Daniels wasn't the only original cast member to get a cameo in the prequel trilogy. In 'The Empire Strikes Back', Jeremy Bulloch played Boba Fett - the most feared bounty hunter in the entire galaxy. Returning to the franchise in the prequel trilogy, he made a brief cameo in 'Revenge of the Sith' as Jeremoch Colton - the pilot of The Sundered Heart.
John Ratzenberger as Major Bren Derlin
Better known as Cliff Clavin from the classic American sit-com 'Cheers', it's hard not to imagine John Ratzenberger propping up the bar. But before his time as our favourite know-it-all postal worker, he was apparently a member of the Rebel Alliance. Appearing as Major Bren Derlin in 'The Empire Strikes Back', he looks like he'd be much more comfortable knocking back a nice cold beer or two… even while chasing down Imperials.
Are there any impressive cameos that we missed out? Who do you think should make an appearance in the sequel trilogy?
