Han Solo never encountered Darth Vader until Star Wars: A New Hope, so unless Lucasfilm wants to rework the timeline a bit, it isn’t likely that Alden Ehrenreich’s Han Solo is actually going to cross paths with Darth Vader.
We now have a report that confirms the presence of Darth Vader in the Han Solo movie.
While it may annoy hardcore Star Wars fans, Rogue One proved that Darth Vader sells tickets.
But since Spencer Wilding was said to be in the Han Solo movie, that led to initial speculation that Vader will appear in the Han Solo movie.
