It's a bit rudimentary, but the House of the Dead: Overkill poster creator offers a great look the basic style of this wonderful game. Use a scrapbooking interface to drop various elements into place, and resize and position them however you like. Then type in your dream cast and whatever helmer you like (as you can see above, what I really want to do is direct). The save it, use it as a desktop, or send it to friends.

Unfortunately, you can't make your own movie title. Also, what the heck kind of House of the Dead: Overkill poster doesn't have a picture of Varla Guns? Sheesh.
