‘If only the reader would play the scene with me, I’d do a better audition!’
A reader is there to help facilitate the audition - not to play the scene with you.
If you’re confused about this you will get diverted and lose focus in your work. Scene partners are your fellow actors in plays and movies or who you practice with in acting class. Develop your ability to know what a thing is – and not what you think it is.
The best readers will make sense of what they say, speak quickly and lightly and leave most of the space in the room for you to occupy.
But they are not and should not be considered scene partners.
Learning this helps you get rid of false expectation, alleviates disappointment and leaves more room for your acting.
