Though Hollywood has more visibility than ever before thanks to social media, be it official posts from actors and filmmakers or spy leaks fresh from the set, you'll still often hear that a movie has unexpectedly wrapped shooting before you even knew it was a sure thing.
While these 15 movies have all been discussed or expected at some juncture in the past, not a single one of them went into production with any significant fanfare at all. In the age of Marvel Studios tooting their horn every time one of their new superhero movies starts filming, it just seems incredibly strange not to make a big deal out of it.
