This is a unique feature of this specific "-CM-" release. While the original film was shot at the standard cinematic 24 FPS, a 60 FPS version utilizes "motion interpolation" or "High Frame Rate" (HFR) conversion. This results in incredibly fluid motion, which can make the action sequences and sweeping camera pans feel more lifelike and immersive.
