Sorry to delay the reply, but here is what I have been told:
Yoda does have a younger brother called 'Yaddle'. Apparently he looks younger and has more hair. (I have since been advised that this is a female character).
The working title for the film is 'Revenge of the Sith'. I don't know if this is old news!
The Jedi are aware of Palpatine's off the ball dealings with the
Empire. Mace Windu leads a Jedi force to go and arrest him at his
office.
They're all inside the room when Palper's refuses the arrest and
pulls the old electric fingers trick! The ensuing battle sees the
remaining Jedi killed, leaving Windu and Annakin left. Obi-Wan's
not there. Mace starts to get the upper hand of Palp, and Palp ends up
hanging from a ledge out of his window hanging on for dear life. He
screams for help, appealing to Annakin, who succumbs to his evil
side and strikes down Mace, as he's been getting more and more p*ssed with all things Jedi. This is the act which confirms him as evil and obviously forces him out of the Jedi.
So when Palpatine rescues Annakin, there's only Obi-Wan left, and
the only way to save Annakin is to have him made into Darth Vader.
Apparently they've just finished shoting that seen and it was ace -
"Arise Lord Vader" and all that sort of stuff! Annakin agrees to
become Vader on finding out that Palpatine has executed Padme.
Annakin is aware that she's pregnant, and wants to track her, but
Palpatine convinces him that she's dead.
Obviously she's not though, she's gone into hiding realising that
Annakin has spun out of control. The rest, as they say, is history!
The final scene is done and dusted. It's basically The Emperor and
Darth Vader standing on the bridge of a Star Destroyer (well, I
presume a Star Destroyer) looking out at the ongoing construction of
the Death Star
hey! that fits in with the rumors Jack, my source at LucasFilm said!
-this is crap. i dont want to see palps. relatives. if lucas puts this kinda stuff in its just plain BAD SCREENPLAY WRITING! if you give a villianous chacter family and such and characters of sympathy, it creates a wierd almost sympathetic view on the villianous character.
