'Casino' turns 25 and more of the best movies set in Las Vegas

The "Hangover" franchise has become a classic in today's comedic landscape. The first film in the trilogy, 2009's "The Hangover," takes place in Las Vegas, where Bradley Cooper, Ed Helms, Zach Galifianakis and Justin Bartha's characters travel for a wild bachelor party gone completely awry. The second installment followed "The Wolfpack" and their misadventures in Thailand, while 2013's "The Hangover Part III" centered around their unfortunate return to Sin City.
