No, not the adventures of Lego Han Solo, which would be cool. The actual, shooting-first Han Solo prior to Episode IV.
The screenplay is written by Lawrence Kasdan and Jon Kasdan. The story focuses on how young Han Solo became the smuggler, thief, and scoundrel whom Luke Skywalker and Obi-Wan Kenobi first encountered in the cantina at Mos Eisley.
First item on the agenda should be to figure out exactly why Han appears to use the term “Parsec” incorrectly. Like, a flashback where he’s in space school and the teacher is drunk, or something.
Now, let the logical Chris Pratt rumors commence! Unless they want to go younger than that, which seems plausible.
