We may have gotten even closer to a true Star Wars anti-hero movie with the Boba Fett movie that was in development several years ago.
So, making a movie from his perspective would have been quite a challenge, but also an interesting angle in the Star Wars universe.
As you may recall, Boba Fett was a ruthless mercenary and bounty hunter for Darth Vader in The Empire Strikes Back and ended up falling into the Sarlacc Pit in The Return of the Jedi.
Needless to say, that movie ended up getting scrapped.
