Trivia: The scene with Jill eating Wesker's sandwich and saying "It's Jill's sandwich now!" (although saying it quickly in such a way that you can't hear the "s" and it sounds more like "It's Jill sandwich now!") is a reference to an infamous moment in the original video game. In the game, Jill is almost crushed by a booby-trap, and the character Barry says she was "almost a Jill sandwich!" The poor dialogue and terrible delivery by the voice actor ended up making the moment a meme many years later.
Trivia: At one point in the film Jill Valentine asks her teammates whether they would rather be eaten by a giant snake or a shark. This is a reference to the original Resident Evil video game were the player has to battle a giant snake called Yawn and a mutated shark called Neptune. Neither of these creatures made it into the film.
