Kurt Russel as Han Solo?!
It almost makes sense, but this...
Robby Benson as Luke Skywalker?!
Thank the Maker that didn't happen! And this! Yikes...
Cindy Williams as Princess Leia?!
She did much better in Milwaukee with Laverne. These next couple are more like it, especially with Harrison Ford reading the Solo part:
Carry Fisher's Princess Leia Audition
Mark Hamill's Luke Skywalker Audition
You can see why George Lucas picked Fisher and Hamill.
