Often, what you see on a screen when it comes to Hollywood blockbusters is not at all what the initial footage looked like. Whether it's CGI, practical effects, models, costumes, make-up or any of the other numerous tactics employed to create movie magic, the finished product is almost always enhanced in some manner, especially when it comes to big budget films. Thankfully, nearly every major blockbuster has its production recorded and documented by photographers and over the years, some truly incredible, exciting and often hilarious behind the scenes photos have made their way online. And so, on that note, join us today as we settle into another edition of our weekly column, where we'll be exploring Joss Whedon's Avengers: Age of Ultron.
