Talk about real looking. My first trip into this museum, I honestly thought one of these wax figures were going to move or pop out at me. I thought that somewhere in this museum they were going to pull a trick on the customers. Luckily, they didn't for my sake.
These "wax people" are made to the same height as the real celebrities. These figures had so many intricate details on them, they are really quite astonishing. The museum showed some of the behind-the-scenes work that went into making these celebrities and the items they used in order to make them look so lifelike. The neatest part about this museum is that you can touch these wax celebrities and get your picture taken with them. In Vegas not many places that you pay to get into will let you take pictures, so this option was nice. I brought back vacation pictures with Brad Pitt and me standing next to each other, and I was surprised at how many people in my office were fooled.
I would definitely go back again, as they switch out the people out quite often and put different wax figures in. You can also visit their website to find out what the celebrity lineup is. See http://www.venetian.com/attractions/madame_tussauds.cfm.
