Star Wars is a franchise known, in part, for its retcons, and while that has at times meant brilliant additions, like Ahsoka Tano being introduced as Anakin Skywalker's never-before-seen Padawan or the clone inhibitor chips being used to explain Order 66, there are just as many examples of this causing trouble for the franchise. While some may be ready to call out Disney for having this effect on Star Wars movies and TV shows, the truth is, this has been a part of Star Wars from the very beginning.

In fact, one of the single most iconic and celebrated moments in Star Wars history is an example of a major shocking retcon: The reveal that Darth Vader is really Anakin Skywalker, Luke Skywalker's father. Likewise, the prequel trilogy was packed with retcons, all of which made it easier to blend the two trilogies together. As common and, at times, critical as these retcons and changes have been in the larger franchise, though, there are innumerable examples of this creating problems for the larger Star Wars timeline.

In fact, the prequel trilogy in particular introduced a host of storylines and plot details that made aspects of the original trilogy more confusing or outright nonsensical, such as Padmé's death taking place mere seconds after Luke and Leia were born, making it illogical that Leia remembered her mother. While that has been slightly explained by Leia's Force sensitivity, there is another example of the prequels creating issues for the original trilogy in A New Hope that hasn't been explained at all.

Uncle Owen Didn't Know C-3PO In A New Hope

Long before the Skywalker family was fleshed out in nine Skywalker Saga movies and numerous TV shows, A New Hope introduced a relatively simple family structure, with Luke Skywalker living on a farm on Tatooine with his Aunt Beru and Uncle Owen. It was clear that something had happened to Luke's parents, and he was particularly interested in learning more about his father. Beyond that, though, the story of A New Hope seemed to reflect a fantastical story happening to an otherwise normal young man.

It therefore made perfect sense that, when Uncle Owen and Luke brought home two droids, R2-D2 and C-3PO, they seemed like random droids carrying incredibly valuable information who just so happened to find their way into the hands of this family. The Empire Strikes Back would, of course, go on to reveal that there was nothing 'normal' about Luke Skywalker, but it wasn't until Star Wars: Episode II - Attack of the Clones that the full connection between these droids and this family would be revealed—and that made this aspect of A New Hope make absolutely no sense.

Attack Of The Clones Revealed Owen Once Lived With C-3PO

After their brutal deaths in A New Hope, it wasn't clear whether Star Wars would ever show Aunt Beru and Uncle Owen again, although they have since had multiple appearances, in Attack of the Clones, Star Wars: Episode III - Revenge of the Sith, and Obi-Wan Kenobi. While it was nice to get more information on Luke's aunt and uncle who met such a tragic end, though, this did complicate things. Specifically, Attack of the Clones revealed that C-3PO had once lived with Uncle Owen and Aunt Beru.

Decades before A New Hope, Owen's father, Cliegg Lars, had freed and married Anakin's mother, Shmi Skywalker, at which point C-3PO had moved onto their farm (the very same farm in A New Hope). Although Threepio ultimately leaves with Anakin in that movie, it's clear that he had spent considerable time with the family already. Given that, it makes absolutely no sense that Owen wouldn't recognize him in A New Hope.

Yes, C-3PO was a protocol droid, and there were many others that looked like him, but there's no denying that he had a very unique personality—one that would be very difficult to forget, especially for Owen, who was always on high alert for connections to Anakin Skywalker, as Obi-Wan Kenobi proved. It's much easier to understand why Owen wouldn't recognize R2, as he only briefly interacted with him, but Star Wars has yet to explain why, despite their significant history, Uncle Owen didn't recognize C-3PO at all in A New Hope.
