This is the first Resident Evil film Paul W.S. Anderson has both written and directed since Resident Evil.
Claire Redfield wears a red vest, her primary outfit from her game appearances.
Alice and her comrades escape the building through the sewers, just like how Leon Kennedy, Ada Wong, Claire Redfield and Sherry Birkin did in Resident Evil 2 out of the Raccoon City Police Department.
In past Resident Evil movies Alice has blonde hair, but in this movie, Alice's hair is entirely brown..
This is the first movie in the series to not feature the Anti-Virus, the cure to the T-Virus.
The first zombie seen in the film (in Tokyo at the beginning of the outbreak) is played by famous Japanese pop star, Mika Nakashima.
With a gross of around $300 million worldwide, the film is the highest-grossing Canadian film and highest-grossing entry in the Resident Evil film series.

Plot similarities and callbacks to Resident Evil 5
In the battle of Chris and Claire against Wesker, many of Wesker and Chris's movements are similar to those in the fight Wesker has against Chris and Sheva Alomar near the end of Resident Evil 5, including the way Wesker throws his glasses to distract Chris.
Jill Valentine returns for a brief cameo in a scene that plays during the end credits, where it is revealed that she has not only survived throughout all of the events of the third film, Resident Evil: Extinction, but also that she, unfortunately, has since become an antagonist, due to a mind control device worn on her chest. This is very similar to what happens to her in Resident Evil 5.
Wesker's second outfit in this movie, after his Umbrella Chronicles tuxedo (also seen in Resident Evil 4), is his Resident Evil 5 midnight outfit.
The large creature holding a large axe, known as the Axeman in this film, appears in Resident Evil 5, where he is called the Executioner.
Due to its purpose in the story as Wesker's base, the Arcadia is most likely a reference to the Tricell tanker from Resident Evil 5.
The tentacles that spew out of Wesker's mouth are similar to Las Plagas from both Resident Evil 4 and Resident Evil 5.
