For example, a theater actor is able to feed on the audience's reactions during live performance, compared to a film actor who does not has this advantage and they have to imagine the plot in their head and represent it as they believe they should. Additionally, movies are created by piecing together snippets of clips. Once recording and filming has been done from different locations, times, etc., technology can be used to combine all the good footage that the editors believe in to create a final product. On the other hand, a live performance means there's only one chance to get everything done and sometimes things don't work out as well as people.
