Kenneth Branagh as Iago

Thus do I ever make my fool my purse:
For I mine own gain’d knowledge should profane,
If I would time expend with such a snipe,
But for my sport and profit. I hate the Moor:
And it is thought abroad, that ‘twixt my sheets
He has done my office: I know not if’t be true;
But I, for mere suspicion in that kind,
Will do as if for surety. He holds me well;
The better shall my purpose work on him.
Cassio’s a proper man: let me see now:
To get his place and to plume up my will
In double knavery — How, how? Let’s see: —
After some time, to abuse Othello’s ear
That he is too familiar with his wife.
He hath a person and a smooth dispose 
To be suspected, framed to make women false.
The Moor is of a free and open nature,
That thinks men honest that but seem to be so, 
And will as tenderly be led by the nose as asses are.
I have’t. It is engender’d. Hell and night
Must bring this monstrous birth to the world’s light.
