It Was a Dark and Stormy Film

Rating: 8/10 (2 February 2008)

The Prestige" is a dark and stormy film, about two rival magicians, Rupert Angier and Alfred Borden. Angier's wife dies in a dangerous escape illusion. Borden tied the knot around her wrists, but he says he's not sure whether he tied an easy-to-escape slipknot, or much trickier one.
Angier seeks revenge, and afterward Borden seeks revenge in turn. Who gets the final revenge? Unless you are paying very careful attention, you won't know even after watching it to the end.
All the magicians are obsessed with the craft of magic, but one is slightly less crazy. And the chances are you won't be sure which is which until the end of the film.
This plot is so rich that you should see the film again to understand the nuances you missed the first time.
After you have seen the film, you can consider reading my second comment, which has spoilers intended to help you understand what's going on.
One thing: I sometimes had trouble telling Angier and Borden apart. To help you: Depending on where in the story you are, Angier has a standard middle-American or an upper-class "King's English: accent. Borden has a lower-class English accent. Also, each of them sabotages the other's tricks at least once. After that, Borden wears gloves to cover his damaged hand, and Angier limps.
