Re: More Star Wars films announced
Another thing that sounds weird in retrospect. In all other movies, "Darth" is treated as a title, not as a name. Ben appears to be using "Darth" as a personal name, and not a title. As if he knows this guy Darth personally. Everyone else just calls him Vader, or Lord Vader.
Chalk it up to a senior moment and move on. It's what I do.
