Monologues leave you all by yourself
Actors have been conditioned to bring monologues to perform at auditions
for the casting director, producer, or director. I’m not a fan of monologues
because rarely do you have a film where the actor is talking for three minutes
straight with no interaction from other characters. Monologues are more
suited in auditioning for stage plays, as they tend to make the actor project
(reach and speak louder).
When an actor prefers to do a monologue, do what I do: Have the actor pick
someone in the room to talk to, and then have that person sit or stand at the
distance he would if he were in the actual scene. This helps the actor better
target his voice level and emotions. You can also have the other person
silently react, so the performing actor has some interaction with a live person.
Doing this eliminates another problem: Many actors who perform monologues
make the mistake of talking to the casting director or person conducting the
auditions (the director or producer) — something akin to looking straight into
the camera, which is a no-no! If you’re conducting the auditions, you want to
observe the performance, not feel like you’re part of it.
