As it turns out, choosing 25 movies to name among the greatest of all time is harder than anticipated; there's a lot of "wiggle room," but subjectivity and objectivity become blurred the further you go. Film is a flux state, and which one goes down in history depends largely on the mood of the viewers; many of the greatest movies also change viewers' moods and mindsets. Besides that, box office success, critical acclaim, and universal appeal play a big role.
Whether you love or hate some of the world's biggest film masterpieces, they're called so for a reason—changing the landscape of cinema, endlessly influencing generations to do something similar, and introducing new and innovative ways to make movies. These are the 25 greatest movie masterpieces of all time.
