We can sit here and list our favorite actors to appear in Star Wars but I find it silly unless and until we know something about the roles available then and only then can we  star our fantasy casting.

Last thing I want is roles created solely to have an actor make an appearance. Let's serve the story first, second and last.

Sorry if I come across as a party pooper

 I disagree that this is a tired franchise.  A well made Star Wars movie will make $1 billion, easily I might add.  If the new production crew insists on making the same mistakes that were made in Return of the Jedi and Episodes I - III then don't bother making any new movies.  The expanded universe has a ton of great stories so stick to the stories and dispense with ewoks, Jar Jar Binks, trite love stories, etc.

No JGL and no Marion Cotillard; no ties to Nolan's last garbage movie.  Where's John Ratzenberger on this list?  A must!

 Yo Rob! Why are there no brothers up on the wall?

I like the list you made Rob.

Here are some of my thoughts:

LUKE - Topher Grace

LIEA - Kate Beckinsale

HAN - Nathan Fillion

LANDO - Jamie Foxx

This would be my top choices.

 Helen Mirren would bring class and substance to the series, much like Sir Alec did back in the day...

I like the list, i like it. The original cast should only appear to pass on the baton to the next gen, maybe Luke should appear more since he is the Jedi master of the time, i like that they are going forward, i hope that the solo twins are included.

 we need Dwayne the Rock Johnson in there laying some smackdown on some sith!

 Helen Mirren as a Grand Moff trying to recreate the Empire under her.  Paul Giamatti an Imperial admiral and her #2, and Tim Roth as a burned out Imperial special forces commander.  Tom Wilkinson as a slimy New Republic politician, Paul Bettany as a Jedi.  Brit Marling as a ruler of a planet  in a strategic location that both sides are trying to woo, with Alfred Molina as her prime minister.

Wiseguy,

I could not possibly have put it in any better perspective than you.  Well done, and I wholeheartedly agree.  

 One thing I noticed about alfred molina. He was probably just starting out, but he had a bit part in Raiders of the Lost Ark. Very beginning, he's the guy who wouldn't throw indy his whip to escape with the golden idol. I like this list, very much a..I don't wanna say next gen star wars-esque line up but that's what it is.
