Pretty cool watching Harrison Ford and Mark Hamill's screen test for the original Star Wars.
The vintage footage was from 1976! (Watch the screen test below)
According to the YouTube caption:
In the mid-1970s, director George Lucas was casting for the now-iconic film Star Wars. Harrison Ford was hired to play the part of Han Solo (as a favour to Lucas, by reading opposite actors auditioning for the role). Harrison proved so good in the readings that he was officially offered the role of Solo.
