A movie line

[Pepperoni Papaya]

I've just heard this on the movie "Black hawk down" and I don't know whether I got it right. So please take a look at this line and show me if there's any mistakes: "You know what I think? It's no matter what I think".
It seems to be a very simple line but I just want to be sure ^^. Sorry if I bother you .

It should be;

It's of no matter what I think.
or,
It doesn't matter what I think.

Could it have been "It's not a matter of what I think"?

(What I think doesn't matter. Something else does.)

The film is Black Hawk Down, and the quote you're referring to is this one:

"Y'know what I think? Don't really matter what I think. Once that first bullet goes past your head, politics and all that sh** just goes right out the window."

Keep in mind that characters in films do not always use correct grammar! ;-)
