You'd think Han Solo would log some air miles flying his plane, helicopter or the Millennium Falcon on Star Wars Day ... but instead he hit the Brentwood Market while clutching the book, "News of the World."

It's not even a sci-fi novel for cryin' out loud -- it's set in 1870 northern Texas!

Maybe Harrison's just reading up for a future movie role, but we think Chewie would be highly disappointed. Then again ... Han's dead.
