O (Cirque Du Soleil) - Set and Technical Information

Set and Technical Information

The show has a cast of 85 acrobats, synchronized swimmers and divers performing in and above a 1.5 million-gallon pool. When maintenance needs to be performed, the pool is drained in about 12 hours to the Bellagio Lake, causing the lake's water level to rise 1 inch (25 mm). The pool is kept at 88 °F (31 °C) and has an underwater communication system and regulators that allow performers to breathe underwater. Every member of the cast is scuba-certified.

The underwater stage lift was produced by Handling Specialty. In order for the platform stage to rise and fall in the water without a wake, the surface of the stage has thousands of tiny holes which were drilled out by the Cirque team.

Heaters under each seat help control the theatre temperature for the audience; the goal is to maintain two temperature zones in the theatre. The stage is kept at a higher temperature while the audience area is kept at a lower temperature. A temperature sensor every few seats in the theatre helps to ensure the audience area is maintained at the correct temperature.

To minimize damage to the musical instruments, the musicians play from glass enclosures in the theater. Some of the musical instruments used in the show are more than 100 years old. The unique string instrument heard in the soundtrack of O is an erhu, a traditional Chinese bowed string instrument.

To maintain a fresh look on the performers, some performers have multiple sets of costumes so they may reappear dry despite having been in the water. Some of the costumes only have a lifespan of approximately 20 shows due to the bromide and chlorine in the water.

Some additional facts about the show include these below.

• Some of the props function as boats, like the umbrella that Le Vieux rides on the water.
• The horses that the Comets ride in the show weigh 900 pounds (410 kg).
• The clown house weighs over 7,000 pounds (3,200 kg).
