Avengers: Age Of Ultron - 10 Things Joss Whedon Doesn't Want You To Know

Secrecy isn't an easy thing to come by in Hollywood these days; something J.J. Abrams knows all too well after Star Trek Into Darkness' big Khan twist was leaked months in advance. His mystery box has sprung plenty of leaks during production on Star Wars: The Force Awakens too, and everything from concept art to major spoilers have surfaced. It's not just him though: the internet has made it impossible for moviegoers to not head into the cinema being as well informed as those who starred in the movie they're watching. As the Marvel movies have grown more and more popular, it's become harder for them to keep everything they would like to under wraps. Whedon certainly managed to surprise fans with The Avengers, but those same fans knew that Thanos would be making a cameo appearance long before the release of the movie. When it comes to Avengers: Age of Ultron, an awful lot of details have found their way online long before they were supposed to. Whether it's a mouthy actor, plot spoilers from various sources, or something else altogether, there's a lot the director doesn't want you to know about the sequel to the highest grossing superhero movie of all-time. Here, we take a look at just ten of those, exploring how they've been revealed and why exactly Whedon would rather you not know. Warning: Inevitably Spoilers ahead.
