Inborn artistic ability is an amazing gift that can be used to convince anyone of anything. But only the elect are celebrated with such a talent from above. What is the right thing to do if you need to enter the role, get used to the image, so that they believe you, and no one doubts the veracity of your manifestations for a minute?
Training, acting training
Previously, you should comprehensively - morally, informationally and physically - prepare for your future role. Any professional actor faces a similar procedure before filming. If you have to play a historical character, find out everything about his biography, check out, if possible, his memoirs, photographs, speeches. Read the script daily, memorizing your own and others' lines. Try to fully immerse yourself in the idea of the project, to catch its spirit.
Do your best in rehearsals. Try to learn how to reliably demonstrate the whole gamut of emotions that your character is experiencing at any given moment. To do this, you must sincerely believe that you have the inner qualities of your character. Hone every gesture, word, intonation or movement for maximum believability in everything. However, in order to avoid unpleasant consequences, be wary of completely identifying yourself with the hero. When recreating someone's image on stage, you need to be yourself. Don't forget that this is just a game.
It is also useful to develop empathy - the ability to sense the feelings and attitudes of others. To do this, you need to really want to understand strangers and not occupy your head with thoughts only about your own person. Feel free to show your feelings, practice spiritual and ethical self-improvement. This will allow you to better control your own emotions, which is extremely important for a successful actor.
Skillfully combine creative impromptu with logical analysis. Brilliant ideas about a role can come suddenly, or they can be born out of prolonged brain activity. Think about the script, your role more often, suggest ways to improve the production, video or film, so that, in the end, the audience is satisfied with the view.
