According to CBR, Boba Fett and Mace Windu (Samuel L. Jackson) almost had a final showdown — one that would not have gone down in the Jedi's favor. As it was finally shot, Windu got yeeted out a window by Palpatine (Ian McDiarmid) in the final stages of his coup. But storyboards exist on Reddit that show a climactic showdown between the bounty hunter and the Jedi who killed his father.
Boba Fett's arc in "The Clone Wars" figures somewhat on his quest for revenge against Windu. It's a shame that Boba Fett never got the catharsis he needed, as fathers and parentage are a major theme of "Star Wars." Darth Vader (James Earl Jones) being Luke's (Mark Hamill) father rather than the man who killed his father was the twist to end all twists. Rey's (Daisy Ridley) parentage became a major plot point of the Disney trilogy, as well as Ben Solo's (Adam Driver) attempts to reconcile himself to his Skywalker/Vader lineage. And of course, none of this would have happened if the fatherless Anakin (Hayden Christensen) had been able to save his mother on Tatooine.
But don't despair Boba Fett fans. Since Windu's body was never seen at the end of "Revenge of the Sith," it's possible he could make a return to the franchise. Fett also seemed to die at the end of the original series, and he's getting his own show now. It's possible Samuel L. Jackson's purple lightsaber-wielding Jedi could appear on "The Book of Boba Fett."
