Developers love to sneak things by us, and the best possible way to do so is in trailers. Even in small teasers there can be countless hints towards possible gameplay mechanics, story reveals, and other subtleties. Often, to find them all, you need to go frame by frame, looking everywhere for everything. Its a bit of a pain, so we decided to take that strain off of you. That's the concept behind Frame by Frame.This time, we take a look at the trailer for Lego Harry Potter: Years 1-4. What's in it? A bunch of silly, silent footage put to awesome Harry Potter music, that's what! Take a look, and let us know if we missed anything. Here's a hint: we didn't, because we're awesome.
