Hi! I watched the movie about the kinematograph. So, let me write the comment on the blog.
I think the setting in this movie was 19-20 century in one town in Europe.
The old man was the protagonist. He tried to invent a great projector for the first time in history. He had a wife. But she was infected in tuberculosis. In addition, she wouldn't tell her husband about it.
During chatting with each other, the old man hit upon the idea how to create a color.Therefore, he succeeded in taking the movie in color. However, after that, his wife fell down and died when he found her. He was disappointed with this accident and obsessed with it even if he became a successful man. I think the next story is he would continue to take movies after losing his wife. He became a famous inventor to create a tremendous movie projector. But he tried not to make a modern movie such as 3D, but made a rather old movie just as the one he took about his wife. So, I'm sure he never forget her and she will remain in his mind forever.
