In my biology class, we just finished watching the movie "I Am Legend" to begin a unit on immunity. I noticed that it appears that all the infected people seem to be white, while the hero, Robert (Will Smith) is black, and the other two survivors he meets, Anna and Ethan, are Hispanic. The inventor of the cancer-curing virus that mutated and caused the disease was also white. I'm just wondering if anyone else noticed this, and what you think about the possibility of racial undertones being present in "I Am Legend." I personally don't think it was purposeful, but I just want to know if anyone else noticed.
