*This one already has a trailer. I am the one who posted for it to be added, but that official trailer was posted about ten months ago. This new one was just posted yesterday, so I'm assuming it is the new official one. It should probably replace the other. This trailer also shows the leads in it which the old one didn't (how weird!).
