Fan Casting Friday the 27th - Part 8: Vader Takes the City (1987)

Mass murderer Darth Vader (Kyle MacLachlan) is resurrected from the bottom of Krypton Lake. After he kills a passing boat's occupants, he stows away on a cruise ship filled with a high-school graduating class bound for Wonder City. Biology teacher Cameron Coleman (Paul Newman) is on board with his niece, Riley (Julia Roberts), who has visions of Anakin drowning as a child. They escape his bloody shipboard rampage, but, when Riley and Cameron reach Stilwater, Vader is close by.
