I need ideas for a monologue for Iago in Othello.I'm thinking of setting it before the play when Iago is waiting for Roderigo.

Here are some
thoughts:

First, consider what we notice in common about
every time Iago gives a monologue:

1. He reveals to the
audience what he is going to do - or - he reveals the truth about what he has already
done.

2. He demonstrates the evil and immoral of his
character while when we see him talking with others, he works hard to manipulate them
from believing he could be anything but innocent.

Another
aspect I would consider if you stage it beforehand is the fact that prior to talking to
Roderigo, he must have heard something about Cassio's appointment to the new position.
This would be a monologue full of jealousy of Cassio and anger with Othello for not
having given him the position.
