lol. I noticed this one of the first times I watched the trailer but never felt like pointing it out. The Portal gun scene is screwed up. The first portal Red jumps into isn't the actual portal. It was just edited in. First off, you can tell because it is blue and so is the portal he comes out of, and second because it looks entirely different from what the normal portal looks like. It's all smooth and it goes into the ground. The other portals are outside the blocks. I wonder why they did this...
