The script for Pirates Of The Carribean: On Stranger Tides was left by studio executives in a UK cafe they were lunching at. This sounds like a recent iPhone 4 situation that ended up badly. Amazingly, it was a huge fan (& honest person) that picked it up, realized what it was and sent it to The Sun newspaper to return to the studio execs. The Sun returned it and all is well. The first three films in the Pirates franchise grossed an astounding $2 BILLION dollars, so there was a lot to lose. The fan refused to even read it as to not spoil the plot for themselves.
This fan should be rewarded for their commitment and honesty! There ARE still good people left in the world. Would YOU have read it? Or even returned it?
