The mystery package in Cast Away was revealed to contain salsa, but the movie never shows its contents. The unopened package becomes a symbol of hope for Chuck, representing his longing to return to his old life. The presence of FedEx in the movie, though initially seeming like product placement, becomes an essential part of the story and enhances the overall narrative.

The mystery of what was in the package in Cast Away has kept fans guessing for decades, perhaps not realizing the answer has already been revealed. Cast Away is an Oscar-nominated survival story in which Tom Hanks plays Chuck Noland, a FedEx worker who narrowly survives a plane crash only to find himself alone on an island for years as he fights for his life. However, while Chuck has a few FedEx packages he uses to help his situation, there is one package he leaves unopened for his entire journey.
