The opening ceremony will take place along a seven kilometre stretch of the Seine, and over 3,000 dancers will perform ten different routines on the day.
As music fills an empty hangar on the outskirts of Paris, dancers perform a series of top-secret routines in front of a giant mirror.
Spectators will see the fruits of their efforts on July 26th when the Olympic Games opening ceremony takes place in Paris.
Organizers are promising something “amazing” but are remaining tight-lipped about details.
A small number of journalists, including AFP, were able to attend just a few minutes of rehearsals this month.
Neon lights and disco balls contrasted with the industrial chaos of the aging but enormous hangar.
Paris Olympics makes history with spectacular spectacle on the Seine
Such a large space was needed because, for the first time in Olympic history, the Opening Ceremony will not be held in a stadium.
Instead, more than 3,000 dancers will perform 10 different routines a day along a seven kilometre stretch of the Seine.
Around 400 people are expected to take part in the section, some of which was spotted by AFP, but there is not enough space for everyone to rehearse at once, so they are split into smaller groups of around 50 people.
“It requires some serious organisation, but we're getting there,” said lead choreographer Maud Le Pradeck.
“There are dancers on every bridge in Paris,” she added.
Her goal is to create a dance that is “diverse,” fusing everything from classical to breakdancing.
As the dancers' sneakers squeaked on the floor, Olympic organizing committee president Tony Estanguet and Olympic artistic director Thomas Joly snuck into the room to watch.
“That's great! I want to participate!” said Estanguett.
While details were kept under wraps, Jolly said all feasibility studies have been completed, and the original plans are moving forward with only minor modifications.
“This has been taking shape since mid-March,” Jolly said.
“The choreography is set, the costumes are out of the workshop, the music is ready. We're ready to go!”
