Creator Killer: Team Bondi shuttered months after release. Though the game was a critical and commercial success, Team Bondi's founder clearly considered it his Magnum Opus and terrible working conditions, high staff turnover, and endless delays resulted. It destroyed the relationship with Rockstar and ensured they would never get another publisher.
Hey, It's That Voice!: KenCosgrove interrogates fellow Sterling Cooper coworkers Harry Crane, Paul Kinsey, Pete Campbell, and client comedian Jimmy Barrett. Dr. Wayne has also became a coroner.
Perhaps it's fitting then that you meet and partner up with the Burned Man at the arson desk. Joss Whedon fans will figure out he's Daniel Holtz. He and Connor actually have a reunion, only most people will probably attribute the latter to his role in Mad Men more.
Agent Davis is an installer for a water heater company.
Elsa's singing voice is provided by Claudia Brücken, best known as the lead singer in the 80s synthpop acts Propaganda and Act.
Carol MacLaren is tending bars across the country, sixty years in the past. Maybe he really is a vampire.
Real-Life Relative: Aaron Staton and Connie Fletcher, who are married in real life, play in-game couple Cole and Marie Phelps.
Troubled Production: Team Bondi's founder ruled the development of the game with an iron fist, chewing up and spitting out a huge amount of prospective employees and subjecting whoever was left to insane amounts of unpaid overtime. The end result was the company gaining the ire of Australia's game development community, Rockstar cutting their ties, and L.A. Noire being Team Bondi's first and last game.
What Could Have Been: Reportedly, the game was originally so large that they had to cut out much of the content just to fit the core story cases onto three disks for the Xbox 360. While several cases related to the existing desks have been released (5 in total, comprising roughly 4 GB of data), there's still a lot more content that is unaccounted for.
This is noticeable at several points, such as a throwaway line near the beginning of "A Marriage Made in Heaven" concerning a girl named Anna Rodriguez, which makes no sense unless you play the PS3 version, where the case "The Consul's Car" is included. Also, "The Naked City" explains Bekowsky's sudden promotion to Homicide, as seen at the start of "Manifest Destiny".
Further, looking at the case numbers in the official strategy guide, large gaps in the number sequence are noticeable. For instance, the Traffic cases skip from 1 to 3 to 5. Since "The Consul's Car" takes place between "The Driver's Seat" and "A Marriage Made in Heaven", its safe to assume that it's supposed to be Traffic Case #2. The Homicide desk is the only desk with a full case number sequence at the start.
The DLC only covers cases cut from the desks that actually made it into the game. The Burglary and "Bunko" (fraud) desks were cut entirely, and although the developers had hinted that they might complete them and release them as DLC, given Team Bondi's liquidation, this possibility now looks highly unlikely. The game hints towards this when you first switch from Traffic to Homicide, subtly by noting a 6 month gap between the two and explicitly when the chief informs the staff that Phelps was promoted from Burglary.
