A good source to get lines from for Epiosde III would be from the Episode II video game that came along with the movie. Al lot of the lines in the game are different then the ones used in the movie. Most of the characters were voiced by the same actors from the movie. Specifically Hayden and Ewan. Could always be useful. Especially with the duel between Anakin and Obi-Wan. The lines in the game differ drastically from the movie duel.
Also, I agree with Bingowings statement above.
