The magaicians of the 19th century, enthralled by the science of optics, photography and electricity, opened the door to motion pictures and thereby rendered themselves obsolete. Any amateur with a pair of scissors can cut and edit a strip of film in order to make a woman vanish, sever a head, burn a body down to the skeleton and reverse time. Talent went out of style.... People either didn't believe Houdini when he said that his tricks on film were real, or they didn't care. Illusion became big bigness, and the magicians were out of work.
