Ok then....Johnny Boy...Wrong answer to my question

Astroboy....Chris Walken - Han, Jodie Foster - Leia, Bruce boxinger (guy from Babylon 5 - name spelt wrong probably) - Luke

I think anyway....

Chris Walken definitely - you could have had Nick Nolte as well. There was also the dude who played Han in the radio plays who also auditioned, but I guess he did 'play' Han in the end...

Jodie Foster yes - Sissy Spacek was another one

Not sure about Bruce Boxleitner (!) but Kurt Russell was an early frontrunner
