the only promo materials that have been released show boba fett's helmet on the poster. its obviously a "bounty hunter"show about hunting down the last of the jedi between episode 3 and 4. the "minor characters" are the bounty hunters from the ISD scene in ESB. Boba probably features as the protagonist and the jedi's (if any) are depicted as the "bad guys".

in other news I heard he's already finished ~30 episodes of the CG clone wars series , and he's already set to sell it to a network so they can start running it on TV, but nobody's buying. he's having a hard time getting it "picked up" by any of the networks because its more of a PG-13 cartoon and its got no place in the network formula. they would have liked a more G-rated cartoon (or a PG-13 "live action") because they have a hard time with the idea of ruinning a "Cartoon" on prime-time TV, opposite shows like Lost and ER, which "adults" will actually watch. the networks don't quite know how to 'Sell' this one. it doesn't fit neatly into the "kid's show" genre , nor does it fit the "prime time" formula. (ie: women won't watch it so it can't go on prime time, and kid's can't watch it because its rated too mature), so nobody is buying.
--> George might have to start his own TV network, just to air his shows before they go straight to DVD. heh
