The illusion is nevertheless perfect, because the spectator misjudges the distances as long as he does not see anything in the neighborhood of the screen.

But if the eye falls upon a woman playing the piano directly below the picture, the illusion is destroyed.
He sees on the screen enormous giants whose hands are as large as half the piano player, and the normal reactions which are the spring for the enjoyment of the play are suppressed.
The further we go into details, the more we might add such special psychological demands which result from the fundamental principles of the new art.

But it would be misleading if we were also to raise demands concerning a point which has often played the chief role in the discussion, namely, the selection of suitable topics.

Writers who have the unlimited possibilities of trick pictures and film illusions in mind have proclaimed that the fairy tale with its magic wonders ought to be its chief domain, as no theater stage could enter into rivalry.

How many have enjoyed "Neptune's Daughter"-- the mermaids in the surf and the sudden change of the witch into the octopus on the shore and the joyful play of the watersprites! How many have been bewitched by Princess Nicotina when she trips from the little cigar box along the table! No theater could dare to imitate such raptures of imagination.
