Morrison, who's portrayed Boba in countless Star Wars projects, like The Mandalorian and anime series Star Wars: Visions, will reprise his iconic role in The Book of Boba Fett. If the show does explore Boba's past, it's possible Morrison might also return as the bounty hunter's father, Jango Fett, in a flashback. Wen has played Fennec before as well, in The Mandalorian and animated series Star Wars: The Bad Batch.
Although there are theories characters like Din Djarin (Pedro Pascal), Bo-Katan Kryze (Katee Sackhoff), Lando Calrissian (Donald Glover), and Han Solo (Alden Ehrenreich) might appear in the show, nothing is confirmed just yet.
