10 Fiendishly Clever Secrets Hidden In Famous Movie Posters

Passengers, starring two of the hottest properties on the planet in Jennifer Lawrence and Chris Pratt, simply didn't live up to the hype that those two mega A-list names warranted.

It was well put together, with some beautiful cinematography and set design, but its central romance and mystery were both lacking.

The above poster contained a mystery, too, on top of the one at the heart of the film itself. What exactly does the series of dots and dashes, placed just below the title text, mean?

It doesn't take a genius to figure out that this is Morse code, but since most normal people aren't very fluent in that particular form of communication, the help of a translator is needed.

The sequence shown on the poster reads "SOS". The movie is about two passengers, travelling on a spaceship, who wake up 90 years too early - and so are stuck, seemingly doomed to die from old age before the ship reaches its destination.

And what do you do when you're trapped on a ship? Send out an SOS. It's a little on-the-nose once the code is actually translated, but this was a smart way to get people to interact with the movie's marketing campaign.
