That Thing That Someone's Probably Already Thought Of

SPOILERS for Cast Away

Today I was thinking about Cast Away, the movie in which Tom Hanks is stranded on a tropical island with a bunch of FedEx packages that he opens in the hopes of finding tools to help him survive. He opens all the packages but one, vowing to deliver that one package if he ever escapes. 

In the end, of course, he does indeed escape and deliver the package. The recipient thanks him and Tom Hanks goes off to to whatever happens next in his life in the world of the film. 

With dark amusement, I imagined an alternative ending: the recipient of the package, excited by its arrival, opens it up...and it's a satellite  phone. Tom Hanks goes "D'OH!" End of film. 

Yeah, I'm sure someone's thought of this already.
