O (Cirque du Soleil) at Bellagio

O is a water‑themed Cirque du Soleil production that premiered at the Bellagio in 1998 and is performed in a custom aquatic theater-in-the-round. The show combines synchronized diving, acrobatics, and theatrical effects using a stage that converts between dry and wet elements. High-quality video clips and photos from O’s performances are frequently shared online and have been repurposed in short-form viral videos and visual memes. O remains a long-running resident production at the Bellagio.
