Dawn of the Planet of the Apes: Worried about ape domination? Scientists have proven that no matter how intelligent other primates become, they will never learn human speech. Their vocal cords can't create the sounds of our speech patterns. At least we'll always have that advantage over them.
Movies are glimpses into these alternate Universes. We don't have superheros or time-travel in our Universe, but there are an infinite number of Universes that do. They are also different in small ways, too... Maybe that Universe had Tic-Tacs in WWII instead of M&Ms. Or, Washington had a baseball team in 1973 instead of a football team. Or, they have technology that allows them to build flying aircraft carriers AND self-resetting air bags.
Oh and Emma doesn't "bang like a screen door" she squeals like one needing oil.
