Came across this today at the Damaris web site while searching for a book on science fiction and faith.
Seems they have a book which
examines the Matrix phenomenon, with in-depth analysis ranging from the science fiction and comic book influences to the philosophical and religious themes that underpin the films.
I see also they have information about using the Matrix trilogy as a discussion tool for small groups with material you can download (including a sample chapter).
While I think that too many Christians have an uncritical view of the films, seeing all the Judeo-Christian symbolism without the other philosophical and religious themes, there may be something here for them to begin to engage more critcially. It may also open the door to thinking about looking at engaging other films too.
