I often see actors audition successfully for parts in which I knew they would not be quite right; that is, their performances would disappoint their director and audience, as well as me. They audition strongly and rehearse poorly. Now, there is no real surprise or dishonor in this. Audition skills--as we know--are particular, and any performer who has them deserves a nod of respect. But, I am surprised that directors don't necessarily see what I see in these performers, and, in truth, in my own auditions I've been hugely overly reliant on what I've been thinking of as the director's ability to see--to have a sixth sense for--how some performances will inevitably grow in rehearsal, and how others will never escape the hard, bright, pushed, brittle presentation in the audition room. By depending on my assumption about a director's 'sixth sense,' I've been hoping s/he would see in ME what I see in ME; that they would understand my own rehearsal process before they'd ever been exposed to it. Bad boy. I'd be better served by not asking directors to read my mind.
So, I need to risk being hard, bright, pushed and brittle in audition, myself.
