A little while ago a made a post about L.A. Noire posting the trailer and pics from the game. Well here is a vid of some game play that passed by me but im posting it now and it looks pretty awesome.
Here is some info about the interrogation aspect of the game.
Each interrogation in L.A. Noire features the same set-up, whether it's a person of interest or a potential witness. You pick from a list of possible questions, listen to the answer (watching your subject the entire time), and then decide if they're telling the truth, holding something back, or flat out lying. The interface lacks an imagination -- a matter-of-fact list hovering in the top left corner of the screen -- but the results are pretty spectacular. Catch someone in a lie and there's an instant sense of satisfaction you rarely get in video game conversations.
The trick is figuring out who to believe. If you haven't been following L.A. Noire, it uses a slick new MotionScan technology that renders an actor's face to perfection. Every furrowed brow, quivering lip, and shifting set of eyes is replayed during conversations, making for true performances on screen. That also means you aren't reading some animator's guess at how someone would act if lying -- you get a trained actor's interpretation of a character. If you've ever watched an episode of Law & Order and tried to figure out who was trying to pull the wool over Sam Waterston's eyes, it's pretty much the same feeling in L.A. Noire.
