Exists a brother for Obi-Wan Kenobi?
Though Obi-Wan genuinely had a brother, it's rather stunning to consider the Jedi are all about no attachments! He only shared this memory with Leia during her early years on the Kenobi series. Though little, this moment is really rather important. It makes logical that Obi-Wan has some residual memories of his brother as Jedi are removed from their homes at such a young age to stop them from developing bonds. These recollections might even be the reason he bonded so tightly with Anakin.
George Lucas obtained the name of Obi-Wan's home planet by what means?
I know; it's somewhat weird, but Stewjon is the name of Obi- Wan's planet. Get it, akin to Jon Stewart? It's interesting since George Lucas joked about this with Jon Stewart during an interview. Now, however, it is canon. It even appears on Obi-Wan's official Star Wars Databank website as well as the comic Star Wars Adventures: The Trouble at Tibrin. Lucas' joke thus truly reflects Obi-Wan's official home world. That's fantastic.
In A New Hope, how did Obi-Wan frightend the Tusken Raiders?
You most likely remember that strange sound Obi-Wan produced in A New Hope. Actually, it was the sound of a Krayt dragon—a terrifying monster Tusken Raiders truly fear. You see, Obi-Wan could only do this because of a power known as "sound mimicry; he was using the Force to create the dragon's sound". Still, the Force is really strong! He seems to be asking the dragon to assist him practically.
Only Alec Guinness is a Star Wars actor nominated for an Oscar.
Indeed, his performance in the film earned him an Oscar nomination—the first Star Wars actor to do so! Given the number of excellent performers in Star Wars, it's sort of ridiculous. And although the films have drawn many Oscar nominations, Guinness's is the sole acting one. Quite amazing is that Guinness actually won his Oscar for Best Actor in a Supporting Role. He really nailed Obi-Wan. With some more Star Wars performers nominated shortly, hopefully. The franchise has really a lot of outstanding performers!
Star Wars featured Ewan McGregor's uncle?
Yes! Denis Lawson, Ewan McGregor's uncle, acted Wedge Antilles in the first trilogy. Lawson really returned to perform in Star Wars: The Rise of Skywalker. That's really cool. It was before McGregor ever started Obi-Wan, hence you can understand how that would motivate him to join Star Wars. Also doing live-action Hera Syndulla in Ahsoka was McGregor's wife, Mary Elizabeth Winstead. I wonder whether the three of them will ever see Movies together. That would be rather grand!
Obi- Wan left for Luke what kind of journals?
Right, Obi- Wan was a quite outstanding teacher. After he dies in A New Hope, Luke discovers information about the Force left in these notebooks on Tatooine. It isn't like a Force or anything how-to book here. It's really more about Obi-Wan's time on Tatooine, safeguarding Luke, and his attempts to establish contact with his former master, Qui-Gon Jinn, via the Force. That Obi-Wan was still working on the Force even after he passed away is very amazing; even more amazing is Luke's finding of these notebooks. Within the family, the force is strong!
