Abi, I'll join group 1 because I really like the imagery in "300." In fact, I pulled some screen shots from it to use as reference sources for some of the characters in my cards for "The Endless" swap. I looked at a site that has screen caps and I decided to choose "Titanic" for mine, only because there is a wide variety of cool imagery in the movie. Screen shots may be found here. Anything that appeals to you is fine with me. You can do the people, the ship, the ocean, things in the wreckage, action shots, whatever you find interesting. Just have fun with it!
