Sorry but that’s just dumb. Why not give the actors who actually portrayed the character for the film a chance? The new casting of Han, Lando, and Chewie (ok so he’d played chewie already in a few films but it’s not Mayhew) is one of the highlights of Solo imo. The new actors really do a phenomenal job nailing the old familiar characters without being just impersonations of previous actors.
Did I buy them as Harrison Ford or Billy Dee Williams? Of course not. But did I buy them as authentic Han Solo and Lando Calrissian? Absolutely 1000%!
