15. S.H.I.E.L.D. Leaked The Movie's Script
Well, not exactly, but Samuel L. Jackson very nearly made a costly mistake when he used a printer in Canada and left behind a digital copy of The Avengers script as a result. It didn't take long for the person who found it to get a copy of their own and start offering it to the highest bidder, but a combination of sites refusing to pay a huge sum for the screenplay and the power of Disney meant that the leak was contained early on. Still, you'd think that Nick Fury would be a little more security conscious! There were rumours that production was halted because of the leak, but both Jackson and Chris Hemsworth denied that.
