Harrison Ford: How Han Solo Has Changed Since Original 'Star Wars'

Harrison Ford talks about an older Han and "the rogue still left" in him.

But Ford admits the "smart-a**," as he calls Solo, has changed in the many years since the original trilogy took over theaters everywhere.

“While we were invited to engage on the questions of some pretty arcane mysteries -- the Force and the mythology that surrounds it -- he was the guy who said, ‘What? Huh? Come on,’” he said of a young Solo.

Now, he says of the older Solo -- who you see in the trailer talking about the Jedi and the Force and how they are "real" -- that "there’s not an abandoning of the character," but there are subtle changes.

"We spend a lot more time [in the movie] on his failure to master basic skills, like accounting. And accounting for his own behavior," Ford added. "There’s a lot of the rogue still left in Solo. Some things don’t change.”

Ford also spoke about his excitement to do another "Indiana Jones" movie.

At 73, the acclaimed actor shows no signs of slowing down and his fans wouldn't want it any other way.

SIDEBAR: Ford told EW he called his own ambulance when the door of the Millennium Falcon broke his leg early on in shooting "The Force Awakens."

"I knew that my leg was likely broken, and I didn’t know what other injuries there were. I was mostly concerned about the long ambulance ride to London. I asked them to bring my cell phone over," he said.

So he called in an air ambulance. And the rest is history.
