Add a character from a different film or TV show to Star Wars and describe a scene!

It'd be to add Ash Williams as a Rebel Grunt that ends up hopping on the Millenium Falcon in Empire Strikes Back after Hoth.

He'll be making the classic wisecracks along the way, hitting on Leia, and trying to one-up Han as they travel to Cloud City.

In the closing elements of the film as Luke meets back up with Leia, Han in Carbonite, he'll see Luke with his new stump and say

I've been there buddy..

Roy Batty simply wakes up and finds himself in the corridor of a ship he didn't recognize. His last memory was of a rainy rooftop chase, where he reflected on his own existence (Tears in rain monologue). There was a clear reminder of the imminent death he was facing, but he was simply there, awake and in an unknown place. He didn't have much time to reflect, a metal door soon opened and a man wielding a blaster looked at him, Roy felt his replicant body lock up, almost without reaction he recognized the man who chased him on that same roof where he died, Deckard.

However, Deckard was very different, both in his clothes and in his company, a large hairy “bear” that made a noise similar to “RRWWWGG” (I imagine you already know who that is hahaha), Roy still tried to hide, but the limited space didn't allow it, ending up having a blaster presented to his face and the question from our favorite charlatan “Who are you, white hair? Tell me immediately what you're doing on my ship”

Roy was immediately startled “Calm down, don't forget what I did for you (I won't spoil it for those who haven't seen Blade Runner, those who have seen the movie know hahaha. Han, without even threatening to lower his gun “I have no idea what you're talking about, but I hope you'll be clearer in your next answer, just know that I'm the one who shoots first”. Roy, realizing that he looked very much like Deckard (the actor is the same, in case you hadn't noticed. Harrison Ford) raised his hands in surrender and began to speak.

“I am Roy Batty, I come from a place where I was raised to fight, but I was persecuted for simply having the will to live,” followed by all the last moments of his previous life. Han lowers his blaster and says: “Around here we don't believe in fairy tales, we live in a world at war... But I won't deny you a ride to the Tatooine cantina. Don't try anything weird, I won't be sorry to eliminate you”. However, Han doesn't fail to feel deep down a certain connection with the strange figure, the simple struggle to live.

Pulp Fiction + Star Wars.

As Mace Windu is about to strike down Palpatine in his chambers, Vincent Vega (John Travolta) from Pulp Fiction casually enters the room, instructed by the Hutts to collect a mysterious briefcase. Completely ignoring the deadly confrontation, he wanders around holding his coat, looking for the case. His nonchalance shocks everyone, including the conflicted Anakin Skywalker, who is stunned by Vega’s total disregard for the drama unfolding.

Reporter on the intergalactic radio:

The twin suns are scorching over the Tatooine desert, the crowd is watching the final rounds of the famous podrace with their breath held. Who will win? Most of them of course have put their hard-earned money on Sebulba, but the young local boy, Anakin was right behind him. Could the young Skywalker accomplish the unimaginable and beat this racing veteran?

But what is this? A new contender is approaching! They are incredibly fast, we can't even see what vehicle they are using! The crowd is going mad, people are shouting as they are trying to push ahead and get a better look! All we can hear is a beeping sound.... could it be a droid? But where did they come from?!

Wait! Someone just claimed to spot a kind of bird running down the track, outpacing every contender!

Is this even allowed? To participate on foot? Doesn't matter, the crowed is loving it, some of them are even putting their bets on this unknown champion who might not be qualified to participate in the race, but definitely they are putting on a great show!

Imagine what a different story it would have been if the Road Runner from Looney Toons run past the podracers and was proclaimed as winner of the race? But a more important question probably is, where is Wile E. Coyote?

I'm going to go down the route of my popular Bounty suggestion a while back which involved recasting Rowan Atkinson in a different TV/Movie role.

I'd bring Mr Bean into Star Wars, and have him be interrogated by Darth Vader about the locations of the rebel forces bases.

Being Mr Bean, all he will get in response is a bumbling mess of incoherent nonsense. It would lead to Bean being thrown into the Trash Compator and promptly consumed by the Dianoga. A sad end for a great character. RIP Bean!
