Okay but why have a Han Solo movie when we could have a Cassian Andor movie?
Han is a great character, but Han Solo is a complete jackass when we first meet him. He’s rougishly handsome, yes, but an entire movie about that will probably get old (especially when Harrison Ford isn’t Han) and full of cliches. Cassian lost his parents, and was a layered character without Luke Skywalker’s help with a backstory almost everyone is curious about.
What if the hypothetical Cassian movie showed him having a motherly bond with someone in the Rebellion, instead of a fatherly one? Maybe there was some woman (preferably of color!) who wanted to help 6-year-old Cassian? What if it showed him slowly becoming more and more hardened, showed every battle he fought in, every time K-2 had to pick him from the ruins of a fight?
Diego Luna and Alan Tudyk are completely ready to be in another Star Wars movie, and Alan especially has been insistent on a Cassian (and K-2) backstory. The two loved working together as man and droid. Let’s give the audience something they want, and have actors excited to do the job that are fit to do it.
Just an idea.
