Arguably, the Han Solo movie will have bigger name recognition with causal and non fans than Rogue One did. Everybody knows Han and Chewie.
But also Harrison Ford is Han Solo to everyone, so I’m not sure how much the public is interested to see a young Solo movie. Even I couldn’t care less about the film but will see it because Star Wars. Hopefully it would be so good that I can see pass the new faces.
He’s also Indiana Jones, but four other actors have played younger or older versions of Indy.
