Back in 2009, Todd Phillips brought a movie to the screen which captured a generation. The first film in The Hangover series was the most popular and, at the time, was the top-grossing R-rated movie of all time, taking $467 million at the global box-office. The film follows a group of guys who venture to Las Vegas for a bachelor party – one in which they wake up having lost the groom. They must try to get over their hangovers and discover what happened the night before. The film is completely set in Las Vegas and heavily features one of the most famous casinos on the strip, Las Vegas.
