When the scheming Chancellor Palpatine (Ian McDiarmid) offers to teach Anakin the secrets of the Dark Side of the Force so he can protect pregnant wife Padmé (Natalie Portman) from a deadly vision, it results in the birth of the Galactic Empire, the downfall of the Jedi, and a dramatic showdown between Skywalker and mentor and friend Obi Wan Kenobi (Ewan McGregor). With Samuel L. Jackson, Jimmy Smits, Anthony Daniels, Christopher Lee. 140 min. Widescreen; Soundtrack: English. Three-disc set.
