Very old but still on the ball...
If Star Wars were set in Barnsley
Chewbacca would look roughly the same except he'd only be about 5ft tall, from Kendray and called Spanner.
He'd have the same amount of body hair but would also have tattoos, would permanently smell of drink and invariably sport either a Barnsley or England top.
Obi-Wan Kenobi would invariably be referred to as Chief or Cocker by his cohorts. People trying to start a fight with him would address him as ¤¤¤¤y-Nobby.
Darth Vader would referred to as 'Elmit Head' or in moments of stress 'that dome-edded get'.
R2D2 would refuse to go out on the streets after 10pm because of the number of drunks who would try to stuff chip papers in his head casing or ¤¤¤¤ on him. He would also refuse to go near groups of young kids at any time because of the high risk of being spray painted/dumped in front of a speeding train/set on fire.
Although proficient in over 3500 languages C3P0 would still be unable to understand anything anyone from Athersley said. He would regularly get beaten up for being a knacker-faced poof from Sheffield.
The Millenium Falcon would have static strips, tinted windscreens and extra-flared exhaust ports. It would have a Barnsley Chronicle I Love Tarn Army sticker in the back window and a St Georges Cross SUN SUPPORTS OUR BOYS bumper sticker.
Princess Leia would get captured by Darth Vader because it's hard to run very fast when you're wearing 5-inch platform heels and a tiny silver mini-skirt which keeps hiking up over your ¤¤¤¤ every two steps. And you've been a heavy smoker since you were 6.
The best way to destroy the Death Star would not necessarily be a desperate all out attack. Two easy ways would be to alter its orbit so it passed through Grimethorpe and tell the locals it was full of Cockneys or leave it unattended in Alhambra car park. Or you could convert it into a huge Takeaway.
Lines from the film as they would be uttered in the vernacular:-
Han Solo - 'I've got a real bad feeling about this'
Translation: 'Am Kackin Missen'
'Bring 'em on! I prefer a straight fight to all this sneaking around.'
'Come right art you ¤¤¤¤¤¤¤s, al tek ont lotton yer'
'Hokey religions and ancient weapons are no match for a good blaster at your side, kid.'
'Bugger the mumbo - wot tha needs is a chuffin gret crickit bat'
