This territory has already been explored through books and comics.
If there is one aspect that can be exemplified by experience, then we see a very high probability of there being a battle between the iconic Jedi Knight and the Tusken Raiders in the upcoming solo Obi-Wan Kenobi film under production.
We don’t yet know what will be the period of the Kenobi film, but, we have three possible scenarios to look at: it could be based on Kenobi’s first chronological appearance in Star Wars: Episode 1 – The Phantom Menace; the Clone Wars era; or the couple of decades that elapsed between the original Star Wars film and the events of Episode III – Revenge of the Sith. Out of these three possibilities, we can pretty much rule out the middle one as the franchise has already covered most of that time in the animated series. The first option also makes little sense as it was a time when there was peace all around, and that won’t make the film much exciting. (Also, the original Star Wars film and its prequel trilogies have deeply explored the “origin of a Jedi” angle that such a film might focus upon).
Now, this leaves us with only one possibility that a Kenobi solo film will have to dwell on the time when he was hiding on Tatooine during a time when the Empire was expanding throughout the galaxy all around him. But then, we must not forget that this 20-year timeframe is not just the only and the lengthiest unexplored part of the onscreen life of Kenobi, but, it is also the most action packed and promising part. Interestingly, this is also the same time frame which has been explored in the other Star Wars solo films. The Rogue One ended just before the time that the 1977 Star Wars started at and if we take into account the ages of the characters, then the untitled Han Solo film will be based just a couple of years before that time. Therefore, this 30 years’ time gap is the ideal hunting ground for Lucasfilm to exploit.
By the looks of it, this period won’t certainly be easy going for the filmmakers. As it has been shown in the previous films, Kenobi is so far away from any contact with the world that he is effectively turned into a myth and his disguise of “Old Ben Kenobi” converts him into a forgotten recluse. While he is not helpless in that existence, he is certainly not a mighty force either. So in case you are wondering what kind of a story can be developed around this premise then let’s tell you it has already been done in the form of a comic book as well as a fan trailer.
One of the most consistent elements of Marvel’s present Star Wars comic book is “ The Journals of Old Ben Kenobi,” which is a diary wherein Kenobi has noted down his expeditions during his time in hiding. While these stories are not as grand and vast scoped as the typical Star Wars plots which show him work secretly and taking on local community dangers such as bounty hunters, criminals or the Tusken Raiders. The crux of all these stories is that Kenobi is attentively guarding young Luke Skywalker and protecting him from all harm. This narrative has already been depicted in the animated Star Wars: Rebels series. Therefore, it is quite apparent that this plot can’t be overlooked by any prospective film based on Obi-Wan.
A short story “The Last One Standing” which came out in 2006 had the same premise showing Kenobi protecting Skywalker, Uncle Owen and Aunt Beru from the attacks of Tusken Raiders and again the 2013 novel Kenobi showed the Jedi Knight rally the locals take on Tusker Raiders and keeping his real Jedi powers a secret at the same time. Although both the mentioned stories are no longer a Star Wars canon, the comic books released by Marvel are. They give a great insight into what kind of life Obi Wan lived during those years of hiding, and these comics are bound to provide the impetus for any story line that is developed for the Obi Wan solo film.
In case this is how the upcoming Kenobi film turns out to be, the fans can be assured about another part of the original Star Wars film being expanded into a solo some time down the line. The Ponda Baba had played a cameo in Rogue One, and he could feature in the Kenobi film that could show us the background of this character and his appearance in the original picture shared below:
