Good point.
I also remember figuring out the twist quite early. The twin character is present throughout the movie but never shown from the front (for obvious reasons). As a viewer you quickly sense that something’s off with this guy, and little by little you realize it’s a disguised twin way before the reveal. To be fair to Nolan, it must not have been easy to film something like that without giving it away too soon.

I still think it's Nolan's best. Also casting Bowie as Tesla was a genius idea.
