Resident Evil: Extinction

Alice mentions that she managed to hack into the Umbrella servers to learn about their satellite movements. There were unused scenes from the original script where Alice got access to Umbrella files that revealed that her real name is not Alice Abernathy but Janus Prospero. This was previously alluded to in the merchandise for the previous film Resident Evil: Apocalypse (2004), where a fake newspaper clipping was released that contained details on Alice, such as that her family started a search for her after she disappeared, and that Alice was simply her code name.

In the council chambers, Wesker's glasses reflect the room around him. This isn't a mistake - all council chambers are identical, and Wesker's holographic cameras would pick up the reflection of his table - as well as the reflections of the other holograms in the room during a meeting.

At the end of the credits, Alice's voice is heard to say "You're just... another asshole".
