Birkin's voice actor in Chronicles and Operation Raccoon City is none other than the one who voiced Frank West.
What Could Have Been: In 2001, Capcom anounced that the Resident Evil franchise was going to be exclusive to Nintendo & the Gamecube. In addition to straight ports of Resident Evil 2, 3 and Code Veronica X, a total of two new games (One of which was the REmake) were released (and remained) exclusive to Nintendo's consoles; and Resident Evil 4 was also anounced as a Gamecube exclusive before Capcom decided that due to poor sales of Resident Evil 0 and the REmake, they would release the game on the Playstation 2 as well.
The original versions of RE2 and RE4, known as Resident Evil 1.5 and 3.5 respectively. Both versions were scrapped due to the developers being unsatisfied with the direction they were taking.
Resident Evil 3: Nemesis was originally going to be a Gaiden Game, a side story to 2, while Code: Veronica was going to be called "Resident Evil 3: Code: Veronica". Nemesis then proved to have a lot more content than what was typical of Gaiden Games, so they took away CV's "3" and slapped it onto Nemesis.
The title may have changed, but CV is still the direct sequel to Resident Evil 2.

Subverted with the voice actors for Claire Redfield and Ada Wong, as they have been voiced by their same actors (Alyson Court and Sally Cahill respectively) for the entire series.
Shout Out: The Red and White Queens, the main character named Alice, the fact that the entrance to the hive was behind a mirror (known less commonly as a looking glass). Do the math.
A character is named K-Mart, because she was found in a K-Mart.
When she encounters Alice Jill demands, "Who the fuck are you?" The Steppers released a rather infamous remix called Who the Fuck is Alice? in 1995.
Shown Their Work: Sienna Guillory, the actress who played Jill, actually watched footage of RE3 and mimicked many of Jill's movements in order to get her character right.
Throw It In: The first movie was not supposed to have the little nudity it did, according to the DVD commentary. Apparently, Milla Jovovich had a Wardrobe Malfunction twice in the same movie. It was left in.
What Could Have Been: George A. Romero wrote a screenplay for and was to direct the first film. It was thrown out entirely when he was kicked off the project. Capcom thought that, while Romero's script was close, it wasn't a full adaptation of the game, and they believed fans would complain about the changes while newcomers would dislike the premise. But confusion sets in when they approved Paul W. S. Anderson's script even though it's a much, much farther cry from Resident Evil.*
In as few words as possible, Romero's script was a rough adaptation of the first game and included all of the main characters, while Anderson's was a completely original story that featured all new characters, and whose only connection to the games was Umbrella, the T-virus and zombies.
Admittedly, there were a few head-scratch-inducing changes in the Romero script (Chris, for example, was turned into a Native American civilian who lived in the mansion and was dating Jill), but all in all, it felt like Resident Evil.It just seems funny that Capcom denied the script for a Resident Evil movie by George A. Romero considering the series is more or less a homage to Romero's work.
The fourth film would originally have had a different story, including Leon Kennedy from the video games. Jensen Ackles was in talks to play him.
The White Queen from the third film would originally have appeared in the first (one of the older scripts for the Alice version, not the Jill and Chris).
LJ was originally supposed to be played by Snoop Dogg rather than Mike Epps.
Had Sienna Guillory not been preoccupied with the Eragon movie, Jill would have fulfilled Claire's role in Extinction. Her dropping out of the third movie caused an entire subplot to be removed, in which Jill is hostile and untrustful towards Alice, due to Alice apparently killing Angie between films while under Umbrella's control. This subplot would have culminated with Jill being infected by a zombified Carlos, and sacrificing herself if the tanker the way Carlos does in the finished script.
