relation with Alice in Wonderland?

It's been a while since I saw it, but I think there was some mention of Charles Dodgson (Lewis Carroll's real name) as well.

Not sure if it means anything, or whether it is just something that Paul WS Anderson puts in some of his movies. There's similar stuff in Resident Evil, too.

No tears please, it's a waste of good suffering.

I just watched this last night! I remember there being quite a few figurines and such that make references to Alice in Wonderland. The main character had a little rabbit figurine in his hotel room, and in the hotel lobby, there was a fairly large red chess piece (the queen IIRC) next to the stairs. There is a checkerboard patterned piece of art hanging in his hotel room as well, which could be a another reference to the chess game from the stories. The final child victim had a stuffed animal toy, which just happened to be a white rabbit. You might argue that the whole idea of running down into the sewer system to find the killer was alluding to 'tumbling down the rabbit hole'. Also, the way these visions of his seem to distort reality (the lights across a whole city block go out as the old woman dies; his hotel room is trashed but is magically restored to normal when he tries to show someone else) could be a way of making it seem as though he is in Wonderland, a place that makes little sense.

I noticed the menu of which you speak at the restaurant read The Hatter Hotel(um, Mad Hatter Hotel, perhaps). Also there was the stuffed rabbit toy in the sewer system(rabbit hole). There was strong symbolism throughout the film with the figurins and Alice the child.

The phrases "down the rabbit hole" and "through the looking glass" are found in many movies. Off the top of my head:

For insatnce, in The Matrix, Trinity bears a white rabbit tattoo whom Neo follows to meet Morpheous. Morpheous eventually asks Neo if he wants to see "how far down the rabbit hole goes" or if he wants to return to his previous state of ignorance. The rabbit hole can symbolise another 'world',hidden realms and dimensions, that are just out of sight but there.

The Recruit. Pacino introduces 'The Farm' with a little hoowah(!) speach(black arts, cloak & dagger)and tells Colin's character that he will be going "through the looking glass" in his training. I usually understand this to be a change of perception(maybe allowing the individual to see said rabbit hole.)
just my thoughts,
gotta split-

also the box is engraved with "curious" and the envelope is labeled "curiouser".
obviously Alice says "curiouser and curiouser" in Alice and Wonderland.
You also see playing cards sometimes, ie. the queen of hearts.

I just saw this movie a few hours ago, it was the midday movie on Australian TV.

I've not read 'Alice' (I must do that!) but I know a little about Lewis Carroll.
That and a wikipedia search of both topics revealed some interesting coincidences/connections:

main character Michael Lewis - Lewis Carroll.

Another meal on the menu was Mock Turtle (or was it Mock Turtle soup).
Mock Turtle was a character in 'Alice' and a pun on the name of the soup.

I wonder if the Statue of Liberty in one of the final scenes is a reference to July 4th, on which date (in 1865) the book was published, and on that same day in 1862, Carroll told a story to three little girls about a girl named Alice searching for adventure..which became the basis for the book.

And how about this?
Lewis Carroll had a stammer, as did the killers in the movie.

In his 1996 book, Richard Wallace suggests that Lewis Carroll was Jack the Ripper, based on anagrams taken from two of Carroll's works. Interesting theory, but rather far-fetched!
