The Difference between Tv/Film and Stage performance.

We talked about the difference of TV and Film acting in comparison to stage acting we decided that when you act on film it needs less movement, less expression and that you need to act with your eyes, so your feeling, imagination etc comes out through them.
With TV acting it's more focusing on who is in the scene and not what is happening in the background.
When on the stage you have to project your voice to the back of the auditorium, but when you are on camera you don't need to project as the camera microphone should pick you up without a problem.
