That’s one of my issues with Rogue One doing these classic character recreations. If they’re recasting a young Han for this movie, why not just recast Tarkin and Leia. Don’t get me wrong, I enjoyed the visual callback, but it seems to take away from the acclaim that Guy Henry, in particular, deserves. It also sets up the expectation that if we ever see young Leia again, she has to look like Carrie Fischer.
Regardless of whether one is for or against the CGI recreations, I don’t think it sets that kind of precedent. The Han Solo film will take place years before RO or SW/ANH. RO takes places days and hours before SW/ANH, and part of the nostalgic feeling that they were trying to summon, especially at the end of that film, was building a direct link to it.
As you’ll recall, this is why a lot of people pretty much exploded when a rumor surfaced that Alden would have a cameo as Han in Rogue One. Indeed, it would have been inconsistent to have only recast Han, and have him look more like he did 10 years earlier than he would a few days later.
Jan Dodonna would be the recasting exception, I guess. Presumably it was a small enough part that they didn’t worry about it. But also, to recreate the Tarkin model they really had to analyze and incorporate tons of footage from throughout Peter’s career. There’s not likely that kind of wealth of visual material for Alex McCrindle.
