Notes as I watch it on my laptop....
May 19th, 2005 according to the trailer
Starts off with old Obi talking from original movie to Luke when he says Vader helped hunt down the jedi yada yada...
First new scene: Anakin turning his head with a cloak and his eyes are yellow and he has an evil face on.
Second: Volcano erupting.
Third: Weird alien type machines walking towards shooting out lava.
Fourth: Vader is sitting in his suit and it is rising up from a machine table thingy
Fifth: (flashing during fourth) one second scenes of Palpatine, Amadala, Obi, R2, 3PO, Mace, Yoda
Sixth (flashing during 4th): What's this? Lots and lots of Chewbacca people? Could this be a Wookie planet?
Seventh: Ships going really fast above Couruscant.
Eighth: Anaking and Padme gettin it on
Ninth: Yoda whoosing his saber
Tenth: Yellow ships from first new movie going fast by with R2's
11th: Mace whoosing saber
12th: More Chewies!
13th: Anakin looking mad
14th: Freaky alien guy smiling that looks like a bad guy
15th: Huge ship being blown up on a planet
16th: R2 doing a CG backflip
17th: Ships escaping from a planet
18th: Anaking and Padme hugging
19th: Looks like Obi and definately Anaking fighting each other as a planet is blowing up in the bg
20th: Two huge ships exchanging fire at very close range
21st: Anaking and Obi fighting and holding down each other. Both are hurt and Anakin looks evil.
22nd: More ships escaping
23rd: Freaky Lord Palpatine guys swinging lightsabers in cloaks.
24th: Ships going kaboom above Coruscant
and that's it.
Looks to me like Vader and Obi fight about something, a planet explodes, Anakin needs life-support costume from damage.
Also like to note that Amadala is not in any of the ending scenes. Wonder if she was killed. It looks like the scenes are jumbled up and not in order of when they occur in movie.
