If I was given the opportunity to make a movie performance on Flowers for Algernon, I would make it similar to the short story that Keyes wrote. The only changes to the text would be worse description of how Charlie pronounced certain words, like genius would be pronounced gen-ass in the text; but I would make it be spelled like giniss, this goes for other words put into the story. Worse lettering for words is the key, using the dictionary can help you get a better background on the main word; jēnyəs is how it is shown in the dictionary.
I would choose a movie because the performance would be like a play because it can explain more emotion with the lighting shinning on the performers and the props would have a better prospective for related things towards people in the audience. The original movie was built on the movie directors prospective mine will be on my prospective, which will be how Charlie started off in the start by explaining himself to Mrs. Kinnian, into an opening scene where the camera would start going into his house window; unlike the scene from the original movie were it was Algernon was running through a maze and the people talking to the doctors.
I would have the scenery in the United States, NC. because it is a very crowded state, also it would be in the future; 2025, because at that time many technology and machinery is going to be improved and used for diseases and such. The technology we have today can be used like what was used in the story; maybe in the future we can have more efficient technology. This would be my prospective from Flowers for Algernon.
