The last time the plot of a major Hollywood movie was built around the oft-repeated but utterly nonsensical myth that humans only use a tiny percentage of their brains, we talked to a professor of neurology to debunk it. Hollywood wasn’t listening. Three years after Limitless, the myth is back in Luc Besson’s Lucy, which has Scarlett Johansson controlling matter when she commands 40 percent of her brain, controlling other people at 80 percent, and potentially unlocking “secrets that go beyond our universe†at 100 percent. As far as manifestations of the old “unlocking the brain†trope go, Lucy’s are among the most powerful. We looked back at a slew of movies built around this myth to find out all the things a human can do when full (fake) brain potential is achieved. Here’s what you can accomplish:
