Know what I mean?
Movie speech is so “elegant”, every word is perfectly spoken.
But reality is like: “um… so you know… I… uh…”… the spur of the moment, non-rehearsed, reality.
Maybe movies should add more “inelegance” to make them seem more “realistic”.
This may one of the reasons Alien works so well as a movie. The actors were often directed to improvise dialogue based on a description or just a few written lines. The conversations feel natural as the actors seemingly struggle to find the right words.
