Dead Calm (1989)

After suffering a personal tragedy, married couple Nicole Kidman and Sam Neill take an extended vacation on their yacht where they encounter Billy Zane coming from a nearby ship where he claims the entire crew has died of food poisoning. For many reasons, they don’t believe Zane and their suspicions are justified. There is so much that is exceptionally silly in this film starting with that first tragedy that really didn’t need to be shown but is laugh out loud funny when it is. While typical for thrillers, Kidman’s character makes so many ludicrous decisions that it borders on unbelievable when she is shown to be actually competent in other areas. The writing separates Kidman and Neill through most of the film and that is its one strength. The two have to battle equally harrowing situations alone.
