Several months ago we reported one such rumor, that the new Han Solo might be making an appearance in Rogue One: A Star Wars Story.
And while we’re ok with Alden Ehrenreich being made up to look like a young Han Solo, we’ve always heard that Rogue One: A Star Wars Story will end just before the opening of Star Wars: A New Hope, which would require quite a change for Han in a very short period of time.
It was implied that before the new Solo made it to his own film, the character played by Alden Ehrenreich would have some kind of cameo appearance in Rogue One: A Star Wars Story.
