9 Most Undeserved Movie Plot Twists

9. A Perfect Getaway: The Two Leads Are The Killers

Adventure-thriller A Perfect Getaway cast Steve Zahn and Milla Jovovich as a pair of newlyweds who take a romantic hiking trip to Hawaii, encountering several fellow travellers along the way. Despite its title, nothing about the movie is perfect. Not the couple's Honeymoon, and certainly not the twist it serves up in the final act.

When people start turning up dead, the film becomes a murder-mystery, but writer-director David Twohy wasn't playing fair when he put the story together.

The first third of the film encourages the audience to empathise with the leads, only to out them as the killers later on. Most viewers would have been shocked to learn they had been duped into rooting for two monsters if it wasn't for one problematic scene.

There's a sequence where Zahn and Jovovich's characters discuss how they believe one of the other couples could be responsible for the murders. Why would they think that when they know full well they did the killings? Nobody else hears the conversation; it's dialogue designed solely to cheat the audience.

This sequence would only have worked if the protagonists' insanity prevented them from even realising they were committing the atrocities, but since that's never established, Twohy sits on a throne of lies.
