the tricks
Are we (audience) seeing these CGI tricks in a way that would have given the audience of the day (in the movie) the same astonishment?
In other words, the rudimentary projection of the ghost that the inspector watched, probably was in fact what the Illusionist used. And may have spooked, confused the audience the way we would be spooked today if it actually was like it was int he movie (with CGI).
The intention of the film was done in such a way that we the viewer could enjoy the mystery as well. I'm just wondering if the Director meant to do this? If so, then I am fine with the "impossible"; orange tree, sword and ghost trickery and just take the tricks for what they "would" have seemed like at the time.
Afterall, I believe the first motion picture shown was of a train coming into the camera and thus seeming to drive right into the theatre - resulting in everyone running for their lives. I think if the Illusionist used the CNN hologram of Will.I.Am even 10 years ago would have freaked out the audience.
