San Diego Comic-Con is full of surprises every year but this just blows our mind! Daniel Radcliffe (who was having trouble getting into the country) finally made it to SDCC 2014. But he also ended up pranking EVERYONE at Comic-Con when he walked the floor dressed as Spider-Man, unbeknownst to anyone! So if you took a picture with a very silent Spidey…yup, that was actually Harry Potter under there!
