Trivia: As initially conceived, the series was meant to be a family drama about the 24 hours that passed before a wedding, with each episode being in real-time. However, the creators worried that this idea wouldn't be exciting enough to hold an audience's attention. So they began to brainstorm other ways to use the real-time format idea they had come up with. They ultimately decided to change the series from a drama to an action-thriller, and thus "24" was born.
