is this the actual ending?

Rating: 8/10 (27 January 2007)

THE PLOT: Alfred Borden and Rupert Angier rise to become world-renowned stage magicians. Early in their careers, they meet and a bitter feud develops as they constantly try to out-do, and even sabotage, the other's acts The events of the past are revealed primarily through each of the magicians' diaries. Borden develops an act called The Transported Man, and an improved version named The New Transported Man, which appears to move him from one closed cabinet to another in the blink of an eye and without appearing to pass through the intervening space. The act seems to defy physics and puts all previous acts to shame. Although never explicitly revealed, it seems probable that the secret of The Transported Man is that Borden, all his life, has been two people; his trick involves extreme use of a twin brother as a double, to the extent that they both live the same life. Angier cannot discern the method that Borden uses and desperately tries to equal him, and with the help of the acclaimed physicist Nikola Tesla For Angier's trick, Tesla successfully creates a device capable of teleporting a being from one place to another, but which has a surprising side-effect.
THE ENDING!!! The first time WHEN angier uses the device in his workshop alone, one of two things happen. The first interpretation is that the original Angier shoots his newly-materialized duplicate dead on the spot. In subsequent uses of the machine for public performance, the original is dropped through a trapdoor into a tank of water, drowning him, leaving only the new "transported" Angier alive. However, it can be argued that the first time Angier uses the device, the first duplicate killed the original, and the other duplicates drowned during the performances. It is believed that the Angier in the new location is a duplicate, and their personalities are exactly alike. The final scene of the movie reveals a long dark corridor, the walls lined with metal-reinforced glass tanks, each containing a secretly-drowned Angier.
Borden again breaks into the backstage area. However this time he sees one of the clones drowning. He is seen watching Angier die, accused of murdering Angier, and sentenced to death by hanging. In the end one of the brothers dies while the other lives on to take revenge on Angier, killing him amid his deceased duplicates RATING 8.5\10
