Warning! Spoilers ahead.
On his Instagram account, Star Wars: The Rise of Skywalker cinematographer Dan Mindel posted a behind-the-scenes photo of the Wadi Rum desert in Jordania, where some sequences of the movie were filmed.
But some fans spotted the Lars homestead set in the photo, and Mindel quickly deleted his post. The Tatooine set was obviously not supposed to be revealed before the release of the movie. (sources: MilnersBlog, _ESS83)
This is another confirmation of JediPaxis and Making Star Wars’ leaks.
According to the leaks (spoilers ahead), the final sequence is happening on Tatooine. Rey buries the lightsabers of Anakin and Leia near the Lars homestead. She adopts the name “Rey Skywalker”, even though she’s biologically a Palpatine. The ghosts of Luke and Leia appear. Rey and her friends watch the binary sunset. The end.
