I am in the process of making a new video regarding the symmetry within the Alien series thus far and I find research to be a very important part of the creative process so much that I end up doing more than I ever use. Better to have it and not need it then need it and not have it. Anyway in the process of compiling my data I took out a bunch of my Alien related books and thought I would share them. This is not everything, but it is a lot. Thank you.
