The performance itself needs to meet certain mechanical criteria such as proper voice projection and enunciation. Proper technique allows us to shape-shift into someone else who may be entirely different to ourselves. Good acting also means being a good partner to your fellow actors. Even if you’ve fully nailed your characterisation you are still a cog within the bigger picture of the scene and production. Sir Ben Kingsley has stated before that he aims to make others in the scene look good – not just look out for himself. You must also be willing to adapt or improvise if necessary while staying in character – for example, if a scene partner misses their cue or fluffs a line.
