10 Movie Rules That Make No Sense
4. The Double Jeopardy Law - Double Jeopardy
1999's Ashley Judd-starring crime thriller Double Jeopardy was a huge hit with audiences, despite being built on a fundamental misunderstanding - whether wilful or not - of the American legal system.
The film's protagonist is Libby Parsons (Judd), a woman convicted of her husband Nick's (Bruce Greenwood) murder. But before she's sent to prison, she comes to realise that Nick most likely framed her and faked his own death.
After being paroled, she invokes the Double Jeopardy Clause, which according to the film's logic means a person can't be convicted of the same crime twice, apparently allowing her to hunt Nick down and kill him without legal consequences.
Of course, anyone with even a basic understanding of the law will appreciate how ridiculous this is, as the real Double Jeopardy Clause only actually applies to prevent people being convicted again for the specific criminal event they've already been tried for.
And so, if Libby killed her husband in real life as she does in the movie, she'd be opening herself up to all sorts of legal action. Not smart.
