If you thought Taylor Swift [1]'s "Look What You Made Me Do [2]" music video was insane, just wait until you see this behind-the-scenes clip. While the video itself is full of hidden references [3], one of the most mind-boggling parts has to be when the singer revives all of her old selves. Even though we thought we had found every last one of them [4], it turns out we were sadly mistaken. In this new video, Swift gives us an inside look at how she brought that majestic "Taylor Mountain" to life while also giving us a glimpse at a few old-school personas we might have missed, including two "Tim McGraw [5]" Taylors. Catch all the action above.
