Actor Allusion: Brian Cox plays Richard Morgan, whose wife killed herself because their (adopted) child's uncontrollable psychic powers burned horrific images into her mind. One year later, in X2: X-Men United, Brian Cox plays William Stryker, whose wife killed herself because their (mutant) child's uncontrollable psychic powers burned horrific images into her mind.
Shrug of God: In the American remake, fans of the film note that the victims of Samara look like they'd been drowned, which would make sense considering Samara's predicament. However, both Gore Verbinski and makeup FX artist Dick Smith said that wasn't their intention. They just wanted to make them look creepy.
Further reinforced by the montage near the end showing Samara's victims, with the repeat of Richard Morgan's line: "You take one person's tragedy and force the world to experience it... spread it like sickness."
What Could Have Been: The original ending for the remake had the video getting placed in a video store dropbox and placed on a shelf of recommended videos. This would have implied that the Ring virus would spread across Seattle and possibly the entire country.
