I don’t know that many people say that because of the story though. It created many of the cinematography methods we still use today. Before it, movies were generally just recreating stage plays in front of a camera. Every scene a stationary shot framing the whole room. No real transitions. For Citizen Kane they tore apart the roof and floor to allow for a camera to get moving shots zooming into a scene and angles not often used before. It changed the way people thought of movies and what they could be. People do love watching the slow decline of the powerful, but that movie is considered one of the best movies for other reasons.
The way I remember that Affect is active. You affect things. Effect is passive, and is the result of something. Affect is a verb (and I think sometimes can be a descriptor). Effect is always a noun. So you can have the resulting effect of an experiment, but if you mess with some variables, you have affected the effect.
Though, in this case, you’re turning the noun into a verb, so you could make the case for either use I think. If you hyphenate it though you can leave it as is without thought. "Streisand-effecting.
Years ago I had a CEO of the company I worked at make a similar comment; “affect/effect. No one really knows which one to use.” So my contrarian, anti-authority ass just looked it up right then and decided to always know.
