Vegas Vacation is a 1997 American comedy film directed by Stephen Kessler in his feature directorial debut. It is the fourth installment in National Lampoon’s Vacation film series, and was written by Elisa Bell, based on a story by Bell and Bob Ducsay. The film stars Chevy Chase, Beverly D'Angelo, Randy Quaid, Wayne Newton, Ethan Embry, and Wallace Shawn. It tells the story of Clark Griswold taking his family to Las Vegas to renew his vows to Ellen as the usual hilarity occurs. The film opened at #4 at the box office and grossed over $36.4 million domestically. Vegas Vacation is the first theatrical Vacation film not to carry the National Lampoon label or a screenwriting credit from John Hughes. Plot After the food preservative that keeps perishable items fresh for years which he helped make has been approved, Clark Griswold finally earns the sizable cash bonus promised to him in the previous film from Frank Shirley. He announces to his family that he is taking them on vacation to celebrate and renew wedding vows with his wife Ellen. Excitement wanes, however, when Clark says they are headed to Las Vegas. His wife and teenage daughter, Audrey, have their doubts, as Las Vegas is not known for its family-friendly atmosphere, while teenage son Rusty appears to be more enthusiastic. Upon arriving in Vegas, the family embarks upon a series of misadventures. The Griswolds attend a Siegfried & Roy show, and they also visit Cousin Eddie, the husband of Ellen's cousin Catherine. Eddie and his family now live in the desert just north of Las Vegas, on what used to be a hydrogen-bomb test site. While on a group tour of the Hoover Dam led by guide Arty, Clark becomes separated from the group after accidentally creating a leak in the dam's interior walkways, and is forced to climb the scaffolding to the very top of the dam to get out, because his cries for help cannot be heard over the roaring water. The next night, they are surprised to find tickets to a Wayne Newton concert have been delivered to their hotel room, along with a dress for Ellen. They go to the concert, only to realize that Newton had sent the dress. While singing, he brings Ellen up on stage to sing with him, and visits at their table. The next day, the family agrees to an "alone day"
