Wow! Not bad, T.
In keeping with George Lucas's style of casting relative unknowns as the main heroes and then more experienced / seasoned actors in the supporting roles here are my picks for casting a STAR WARS (Original Trilogy) re-make:
LUKE SKYWALKER: I'd suggest relative newcomer
Josh Henderson, from the TV series "Desperate Housewives".
PRINCESS LEIA: I'd suggest relative newcomer
Jessica Lowndes, also currently appearing in TV's "90210". She's tough, beautiful, and can act. She can easily portray the pedigree of a royal Princess, and a tough gun-totin' revolutionary. Plus she'd look so darn cute with the "cinnamon bun" hairstyle.
HAN SOLO: My pick would be David Duchovny. Rough around the edges, sardonic, cynical, and a bit of a bad boy. Nuff said.
CHEWBACCA: My pick would be Ron Pearlman. Big guy who's clearly comfortable wearing make-up and bulky costumes for a role.
BEN KENOBI: I'd go with Ian Mckellen. British and dignified. Perfect.
DARTH VADER: I suggest casting (former Pro Wrestler) Dwane Johnson (to wear the suit) and Michael Clarke Duncan dubbing the vocal performance.
"The Rock" would basically be turning in a physical performance here. The guy can move, and he's played sword-wielding warrior types before. This guy is highly underrated as an actor. He's really got a lot of talent.
C-3P0: Gary Oldman would make a great "manic British butler" interpretation of the character. I'm also thinking of his prissy Professor Smith portrayal in Lost In Space back in '98. The comedy in the character could come from his sarcastic "Alfred the bulter" -type delivery. I see this updated version of Threepio as "faithful droid with a bit of an edge".
GRAND MOFF TARKIN: I think
Colm Feore would be excellent. He played amazing British-like villains in the past in "Titus" and the "Chronicles of Riddick". And that face... Those ice-cold eyes and those sunken cheeks. Brrrr.... I
totally see this guy gleefully giving the order to vaporize Alderaan.
LANDO CALRISSIAN: Shemar Moore has the looks and the acting chops to pull off the suave Cloud City Administrator.
BOBA FETT: Jet Li. I would make that character
far nastier, more deadly and more vicious. He'd wear the same armored suit, but rely much more on his speed than on his weapons.
