10 Confusing Movie Questions We Still Don't Understand

Robert Zemeckis' Cast Away follows Tom Hanks as Chuck Noland, a FedEx analyst who finds himself trapped on a remote island after his plane crashes.

When Chuck begins to lose hope, he opens the FedEx packages that washed up on shore, finding items to help him survive. However, he decides to leave an angel-winged parcel unopened, promising to ship it himself when he makes his way home. After Chuck is rescued four years later, he stays true to his word, personally dropping the box off at its destination.

Of course, the contents of the package aren't as important as what it symbolises, since it encouraged Chuck to carry on, even when the odds were against him. As such, nobody should care what lies within (unless it was something that would've been handy on a deserted island like a satellite phone). 

But since human beings are curious creatures, it's next to impossible not to wonder what the package contained.

Now, Zemeckis could've put an end to this confounding question by clarifying the matter. Instead, the Back to the Future director has remained hush-hush, causing the mystery behind the FedEx box to linger ever since.
