ET The Extra Terrestrial (1982)

The original: Alien visitors leave behind one of their own, who befriends a small boy in suburban America.

The two not only become friends but are linked empathically. If only they could find a way to get the alien home...

The Kaufman version: ET is a cuddly, telescopic-necked visitor from space during the day, but when night falls, his second, secret career as a CIA hitman comes to the fore.

While Elliott and his family are sleeping ET bangs a bunch of hot Euro chicks and poisons Julia Roberts.
