While acting can be learnt, it being more of a psychological matter better actors usually are those born with more emotional capabilities (emotional intelligence) besides their (general) intelligence. Consider, for example, the cases of such well-known living actors as Ben Kingsley, Nick Nolte, Jack Nicholson, Leonardo DiCaprio, Christopher Eccleston, Kate Winslet, etc. These actors, with their excellent performance, can hold our breath in almost all films they are in. While there are definitely cultural elements influencing our actor performance judgement, there are also psychological truths (if excluding the cultural specific rationalities though they are interrelated) that transcend racial and cultural boundaries which definitely affect us universally though in various ways in various cultural contexts and this helps us appreciate performances of actors from across the world, across cultural boundaries. And the principles of human reasoning are not too different across racial, cultural, political and economic boundaries (if very much different ever) to preclude mutual understanding among these diverse people.
A good script acted out and animated by good actors is an intense experience. This connection (between the script and the actors) cannot be exaggerated. There are innumerable examples I can cite of good acting/performance in movies. One is the virtuoso performances of (especially) Kate Winslet and Ralph Fiennes in The Reader (Stephen Daldry, 2008). The performances of other important actors (especially David Kross for the 15-year old Michael Berg) are also excellent throughout the film. The tear-jerking prison scene toward the end of the film which I am sharing below stands for the excellent actors performance in the film. Please watch carefully, and see against the dialogue (what they say) how every aspect of their acting—how they mime, bear their bodies, how they shift their eyes, put their hands, how they move parts of their bodies, everything, everything about their performance in this scene—plucks the feeling strings of your heart.
