Who was the first to say that "movies are the art of regret" and why?

Movies are the art of regret. I first heard it from Marc Fitoussi, who is a new generation of talented French directors and screenwriters. But I'm really not sure whether he said it first. The director loves to say this sentence, and critics often say it. Directors have two attitudes when they speak. One is amazing. After filming, they felt that their artistic ideas had not been realized. "At that time, if only this. There is no way out. It's a pity. " ; One is perfunctory, "I know this, there is no way to solve it, so this is the only way." Critics say there are also two attitudes. One is to cherish, thinking that as long as you pay a little attention, you can avoid regret. The other is to excuse yourself and think that movies are not like dramas. If you are not satisfied with this performance, you can change it at the next performance. Movies are a one-off art, so it's a pity, but you can't.
