After writing and directing the first Resident Evil movie, Paul W.S. Anderson restricted himself to writing the first two sequels whilst allowing other hands to direct; for the last half of the six-movie sequence, Anderson would handle the direction himself as well as doing the writing. By this point, he and series lead Milla Jovovich had married, making it a sort of horror-action power couple franchise like Underworld ended up being. (In fact, by the end it was a family affair: due to the passage of time aging previous child actresses out of the role of the Red Queen AI, their daughter Ever got the Red Queen role in The Final Chapter.)
Over the course of the first three movies, the story had covered most of the ground of the first three games – with the original movie doing the “bad shit in a lab under a lonely mansion” angle of the first game and Apocalypse incorporating the “zombie apocalypse in a city with a big bad zombie stomping around” of 2 and 3. With Extinction, the plot of the movies pushed on into original material, which the next three films would also follow. Would The Final Chapter find this zombie saga shambling to a halt, or go out with one final headshot?
Resident Evil: Afterlife
At the end of Extinction, it seemed like Anderson had written himself into a corner – with Milla Jovovich’s character Alice not only having absurd superpowers, but also an army of clones of herself who all also had the same T-virus-invoked superpowers. It’s only natural that he starts the next movie by neutralising most of these advantages – but nicely, rather than simply retconning them away he instead allows Alice to play the hand she’s dealt and make use of these resources in a devastating attack on the Umbrella Corporation headquarters. (There’s a nice shot of a security map indicating the spread of Alice-clone incursions into the base that subtly parallels an earlier shot showing the progress of the T-virus plague around the world.)
