[evil twin]

It's a difficult movie to figure out. The first time I saw it I fully bought that Tesla's machine worked and thought it was a bit odd that the movie was actually fantastical. I still enjoyed it immensely though. Once the DVD came out I watched it again and began to question my previous interpretation.

After the third viewing I think I could make a semi reasonable case for Teslas machine not actually working and Angier in fact pulled off a huge trick and we as the audience were also fooled. I really need to watch it again with all that in mind to actually be able to articule my thoughts on the matter though. I think a link to a possible non-magic explanation was posted earlier in this thread or perhaps a different thread.
