Here was an earlier extortion scene. I always questioned the excessive darkness and believability of the scene from the movie, then what's-his-name pleads guilty to trying to have sex in a men's room.

INT. STATE SENATE FLOOR - DAY

The Senate is in session; Senator Geary is on the floor
during a vote. An aide approaches him, with a slip of paper.

INT. GEARY'S OFFICE - DAY

The Senator steps behind his desk.

SENATOR GEARY
All right, Mr. Hagen, you've got
ten minutes.

He flicks the switch of a small tape recorder.

SENATOR GEARY
...and the tape will be running.

HAGEN
Actually, I've come with good news;
the Corleone family has done you a
favor.

The Senator immediately shuts the tape recorder off.

SENATOR GEARY
What the hell are you talking about?

HAGEN
We know you're a busy man, with
plenty of enemies -- we saw the
opportunity to do you a favor, and
we did. No strings.

SENATOR GEARY
No strings.

HAGEN
You know there's a Senate
Investigating Committee recently
set up; we thought it would be
unfortunate if they were to trace
anything though-provoking to your
name.

SENATOR GEARY
No one can trace anything to me; I
pride myself on that.

HAGEN
Do you gamble?

SENATOR GEARY
A little; what's so thought-
provoking about that?

HAGEN
Do you owe markers?

SENATOR GEARY
Maybe two, three thousand dollars.

Hagen leans forward, and deposits a handful of paper on the
Senator's desk.

HAGEN
The Corleone family has paid them
off for you...as an expression of
our esteem.

Geary quickly looks through the paid markers.

SENATOR GEARY
There's thirty grand worth of paid
off markers -- I never owed that
much.

HAGEN
Our mistake. But what does it
matter; it was our money.
(rising)
We don't even expect thanks.

SENATOR GEARY
You paid off thirty grand I never
owed.

HAGEN
We'll keep it quiet; the people who
know are trustworthy...the Committee
needn't find out.

SENATOR GEARY
And what's the price of their not
finding out.

HAGEN
Simple. Be friendly like us. Not
hostile.

SENATOR GEARY
(he despises Hagen)
Thanks...friend.
