The Illusions ARE Real
I've read a number of posts on this board, most from the comparison threads of The Prestige and The Illusionist, of people commenting that the Illusions incorporated in The Illusionist, being impossible, made them think less of the film. However, every single Illusion displayed in the film are actual illusions that have been performed by real illusionists at one time or another. Everything from The Traveling Magician, to The Marvelous Orange Tree Including the "butterfly" ending, to Jessica Biel's puzzle locket. And everything in between. The Painting, The Sword, The Ball, The Mirror, The Chair, The Apparitions. All of them. Also, towards the end of the movie where the "Spirits" appear... That was actually performed in the 1800's as "Pepper's Ghost," invented by Henry Dircks in 1862. "Pepper's Ghost" is still used today at the Disneyland theme parks around the world in several attractions, most notably in The Haunted Mansion and The Twilight Zone's Hollywood Tower of Terror.
There's a mad man in there with his hand on a...on a BUTTON!
