Out of the many, many fascinating characters that Rogue One: A Star Wars Story introduced, one of the most prominent was Saw Gerrera (who existed already in the Star Wars universe prior to the film, thanks to his brief role in The Clone Wars series). Played by Forest Whitaker, the character's role not only in Jyn Erso's life, but in the entire political machinations of the Rebel Alliances seemed to be one of the largest, most interesting tangents that Rogue One briefly glossed over.
In result, the character's arc from a passionate freedom fighter in The Clone Wars to the paranoid, barely alive leader that was shown in Rogue One has been one shrouded in a veil of mystery. Apparently, fans aren't the only ones intrigued by Saw's life in the galaxy either.
As reported by Empire (via /Film), Kathleen Kennedy briefly discussed the original plans for Saw in Rogue One (that were eventually discarded due to time constraints), and teases some further, Saw-centric projects fans can possibly look forward to sometime in the future:
"To be honest, we originally thought we were going to develop Saw into something much larger, but we couldn’t accommodate it. So he is not in the movie as much as we would like to have him in the movie, which creates the opportunity to explore his character even further in our future development."
Whitaker, while in the dark on what exactly those plans might be, seems more than up for whatever it is Disney and Lucasfilm have in mind for his character:
"I’m curious about what else they’re about to do. Because they seem to really like the character, which is great!"
Now, it's already been announced that the next time Star Wars fans will see Saw is in an episode of Star Wars Rebels next year, where he'll be voiced by Whitaker. Combining that with how much of him was featured in The Clone Wars, his appearance in Rogue One, the small role he had in the Star Wars: Catalyst novel, and the overall outline of Saw's arc and life has already been revealed. So it's interesting that Disney and Lucasfilm want to fill in a number of the gaps in his storyline.
Predictably, Kennedy doesn't specify in what medium the studio plans to explore the character. But with the opportunity to continue to tell various standalone stories set in the Star Wars world now wide open following the successful release of Rogue One, it's exciting to see where the creative teams' minds are at, at least partially, when it comes to the future of the Star Wars universe across all mediums.
