O - Cirque du Soleil
O is a water-themed stage production by Cirque du Soleil, a Canadian circus and entertainment company. The show has been in permanent residence at the Bellagio in Las Vegas, Nevada, United States, since October 1998. O, whose name is pronounced the same way as eau, the French word for "water", takes place around and above a 1.5-million-US-gallon (5,700 m3) pool of water. It features water acts such as synchronized swimming as well as aerial and ground acts. The O theatre, which is designed to resemble a 14th-century European opera house, has 1,800 seats, thus allowing the performance to be watched by 3,600 people a night since the performance usually plays twice in a given day, also designed to meet the special demands of the show.O was inspired by the "infinity and elegance of water's pure form," which pays tribute to the beauty of the theatre. A group of 150 stage technicians assist in the production of the show, the cast of which is 85 performers: international acrobats, synchronized swimmers, and divers. Some of them are former Olympic athletes.
