News: L.A Noire: 50 hours of dialogue recorded - ComputerAndVideoGames.com
"We captured over 50 hours worth of dialogue in total, all using MotionScan - it's equivalent to about two full seasons of a TV show," he said.

Of course, we're probably not looking at a fifty hour game here, a good chunk of that dialogue could never see the light of day.

Most of it, however, sounds like it will go towards creating an adventure with plenty of different routes for fans to take:

"Each case has its own twists and turns depending on the choices you make," McNamara continued, "leading you down different paths on your way to cracking the case, giving you plenty of reasons to jump back in and replay the game."
