It is not always possible to look at the actor's performance and believe in what is happening. Some gestures, postures, verbal and non-verbal ways of presenting oneself - all of this seems fake and unworthy of attention. However, with a real actor, everything is different.
“I don’t believe!” - Stanislavsky liked to say to actors who did not get used to their roles. And he was right. A person is not always able to reincarnate in the role that he plays. The audience can not always be made to feel what is happening. Only a masterful game gives the very impression that makes you cry and laugh, worry and listen to what is happening.
A real actor can be recognized by certain characteristics. The main one among them is the ability to get used to the role. There is even a special "immersion method" developed by Stanislavsky. A person immersed in a role seeks to get along with his character as much as possible. So that it was impossible to distinguish between the game and the real life. Of course, this requires skill, some experience and inner work on oneself.
Each of you has the right to say “I don’t believe!” To the acting only if you can do better.
Based on this, one can hardly call an actor of one role talented, since there is rather another side of the issue. The person from film to film shows the same image: a sullen superman, a merry fellow, a loser, and so on. Such an actor, if he succeeds in playing a different role, is difficult to perceive differently than in his usual role. Such a person is hardly talented.
It's another matter when the master is different every time. In a comedy he is a merry fellow, in a tragedy Shakespeare himself would envy him, in a soap opera he is who he should be in his role. It is very difficult, but it gives the maximum variety of roles. The viewer expects that his favorite performer will delight him and surprise him once again. And when you really believe in such a game, only then real talent manifests itself.
If you see how an actor gets confused, stumbles, looks at the camera, makes unnecessary movements in this or that case, maintains illogical pauses, strives to express himself with might and main, but nothing happens, remember - you are a mediocrity. Uncertain performance can only be seen by specialists, but even amateurs are sometimes able to notice the faint embodiment of the image on the stage or in the cinema.
As practice shows, even a mediocre person has a chance to break into talents if he works on himself.
The first mistake a bad actor makes is the inability to maintain a balance between weak acting and overexposure. A professional intuitively feels where the line that cannot be crossed and the bar below which cannot be dropped is. The opposite is the game of mediocrity, visible to the naked eye.
