Han Solo? Yeah, if he happens to have a Time Warp accident. Harrison Ford is OLD now....
Laz...dude...you're not getting it. It's so obvious. The episode that is being made now predates the "first" Star Wars that came out in 1977. That's why Anakin (Darth Vader, Luke's father) appears as a little kid and Obi Wan (Alec Guiness, God rest his soul) is a young man in the most recent episodes.
Harrison Ford could probably be Han Solo's dad in the time line for the next Star Wars. In the Star Wars' to be released time frame, Han Solo would have to be a kid probably younger than Anakin. But Chewbaca, as Wookies are much longer lived than humans, might be the right age. Boba Fett...hmmm, was he the basis for the clones? His story needs to be told and he is in this current time line.
