10 Greatest Unspoken Star Wars Movie Plot Points

If you call yourself even a casual Star Wars fan, the death of Obi-Wan Kenobi (Alec Guinness) is basically seared into your mind, and yet it's easy to miss a pivotal detail that's basically hiding in plain sight.

Obi-Wan of course sacrifices himself during his lightsaber duel with Darth Vader (David Prowse), in turn allowing the heroes to escape the Death Star.

But take a close look at Obi-Wan in his final moments, and you'll observe that he only lets his guard down after first seeing Luke and Leia (Carrie Fisher) making their escape.

Obi-Wan even lets out a wry smile in the seconds before Vader ends him, meaning the last thing he sees before laying down his life is Luke and Leia, the twins he separated at birth 19 years earlier, reunited.

While it's no secret that George Lucas hadn't planned out Luke and Leia being siblings at the time of shooting A New Hope, and this is really more a case of serendipity at play, it still works perfectly for the story that was ultimately told.
