The screen-test between the two movie stars was revealed over the weekend in unearthed an unearthed video.
The black and white footage surfaced on Twitter and showed the initial chemistry between Hamill and Ford during their first screen test for the roles of Luke Skywalker and Han Solo.
Both stars were rounded up by George Lucas, who refused to tell them what the secret movie was about. We now know the scene had to do with the Millennium Falcon encountering the remains of Alderaan, Princess Leia's home planet.
After begging for some back story, Ford filled in some of the details.
“My screen-test for @starwars w/ Harrison on the 1st day I ever met him. Neither 1 of us had read the script at this point, only this 1 scene," he explained.
