Someone’s got to go, either the clone or the original.
That’s the rub in “Dual,” a new film in which a young woman who, after a brush with imminent mortality, is told she’ll likely have a long, healthy life. That is, if she can defeat the clone she commissioned to keep loved ones from having to mourn her.
Karen Gillan, who plays protagonist Sarah and her double, loves the premise of the film, which opened Friday.
