Even Michael Caine told him although he said it was a double but he figured it out too.
Also, did the wife Sarah figure it out? Is that was she was going to tell ScarJo but killed herself before she could?
I never thought of this angle that I saw in some comment section:
"you guys are all being misdirected, as was the idea
The entire film was an intricate illusion by the greatest magician in the movie CUTTER
cutter was behind the entire thing, he was working with angier as a mentor, and brought borden on beaucse he believed borden was a much better magician (as he say to angier when th two meet for the first time)
in the beginning of the movie while in court the judge asks cutter to explain the Transported Man, and Cutter says " i have the right to sell it on if i give you the secret to it the trick is worthless!!"
there you have it, Cutter was the man behind the transported man, he is the one who lead Borden to Tesla to begin with to help him, becuase he knew he deserved it.
Then borden uses it once, creates a bond with his clone and destroys the machine like tesla told him to, when angier buries his clone he gives the real secret TESLA to angier, angier then gets the clone machine and abuses it by killing his clones every night, at what point Cutter sees how perverse and crazed he has become, then helps borden to develop a way to beat him, and leads borden to angier at the end when borden kills him."
Wife never figured it out .. I think the daughter did though
