im not sure if this qualifies as a scene as it never made it into the final cut of ROTS but its one of my faves, in the deleted scenes, there is a segmant that shows General Greivous, Obi-Wan, Anakin, droids and.....*drum role* ...Shaak Ti. There is a few moments of banta between Grevous, Ob-Wan and Anakin, then Grevous kills Shaak Ti. And thats when the fun begins the two jedi decide on what to do and eventually end up cutting a hole in the floor and falling to a sub level refule and hydration center. They make their escape, and anakin seals the hatch using his lightsaber. This quickly brings on the under-estimating words from Obi-Wan "It will never hold" there is an explotion and guess what..... the hatchway holds in place although with what seems to be a rather large super battle droid head shaped dent in the metal work. I rather liked this scene as it explains what happens to Shaak Ti. And i really dont understand why they didnt finish it. Instead of re filming the first encounter between grevous, obi-wan and anakin they could have just left it in with a few tweaks, i beleive this would have given the opening sequences a little more depth and fealing to the characters, the way it did to luke in ANH when he saw his aunt and uncles bones on the desert sand of tatooine.
