Gary Farber has a long, interesting post on Revenge of the Sith, including a link to the original script and discussion of deleted scenes, some of which might have been useful to developing the plot. (via Instapundit). Farber and his commenters stress the usefulness, in understanding the broader story leading into Sith, of checking out the animated Clone Wars series and the Lucas-authorized novel Labyrinth of Evil, which leads directly into the opening of Sith. I missed the series but I’ll probably check out both, eventually.
Also, Orson Scott Card has a big-picture review worth reading (via Will Collier).
In addition to busting several box office records in the US with a $160 million opening weekend, Sith had “the most successful film-opening in UK cinema history” and “grossed $144.7 million overseas for a total of $303 million worldwide,” including more than $26 million in the UK and $22 million in France.
