12. I Am Legend (2007)
This classic Richard Matheson novel turned Will Smith blockbuster sees the Fresh Prince as the last man on Earth. How, you ask? He's immune to a man-made virus originally meant to cure cancer. But instead, it turned everyone it didn't kill into vampires. Again, while he loved the movie, Martin finds the whole vampire/zombie virus problematic. "The viral-vampire element to it is not that realistic. There aren't too many viruses, that we know of at least, that could create a zombie-like vampire plague. Some scientists say that if you mix something like the common flu, that's spread via human by being airborne, with something like rabies, that makes people very angry and aggression-based, that you could have some kind of being that's created like that. But there are millions of viruses that we know of, and there's a dozen new ones popping up every year, so the odds of one being zombie/vampire- based are just enormously low."
