I don’t know if anyone else has made this observation, but I just realized it upon another viewing.
In ‘Solo’, when on Kessel, many people have caught on to the fact that the “Calrissian Chronicles” recordings that Lando is making are referencing the old Brian Daley Han Solo trilogy. That on its own is rather amusing, but I think there may be a deeper level to the joke.
Unless I’m mistaken, part of the concept behind the Legends rebranding is that they’re stories that exist AS stories within the universe. Combine that with the idea that Han Solo was a pop-culture hero in-universe and…
I’m reasonably certain there was a meta joke being made about the Daley Han Solo novels actually being stories of Lando that Han has gone and substituted his and Chewie’s names into.
