Disney (DIS) announced on Tuesday that it was adding two new nighttime spectaculars to its 50th-anniversary celebration of the Walt Disney World Resort.

The events, which will begin on Oct. 1 and run for 18 months, will include the Disney Enchantment spectacular held at Magic Kingdom Park and the Harmonious spectacular held at Epcot.

Disney Enchantment will launch the 50th-anniversary celebration of what Disney is billing as “The World’s Most Magical Celebration.” The celebration will feature music, lighting, fireworks, and for the first time, immersive projection effects that extend from Cinderella Castle down Main Street, U.S.A.

Harmonious will be one of the largest nighttime spectaculars that Disney has ever held at its park, which the entertainment company said will “bring the globe together at World Showcase Lagoon in a celebration of Disney music that inspires people worldwide.”

The event will pay tribute to the stories and songs that unite us, Disney said, with new technical magic that incorporates pyrotechnics, choreographed moving fountains, lighting, and media set to classic Disney songs “as you’ve never heard them before” in more than a dozen languages performed by 240 artists from around the world.

Mickey Mouse and Minnie Mouse will be the hosts for the 50th-anniversary celebration at Disney World with sidekicks Donald Duck and Daisy Duck, Goofy, Pluto, and Chip ‘n’ Dale appearing in the new Mickey’s Celebration Cavalcade several times daily throughout Magic Kingdom Park.

The eight characters have also been emblazoned as golden sculptures, which will debut on Oct. 1 in Magic Kingdom for a total of 50-character sculptures that will be unveiled in the four theme parks during the anniversary event.

Also new for the anniversary will be the opening of Remy’s Ratatouille Adventure at Epcot.

Disney said more information about the 50th anniversary spectacular will be share in the coming months.

Disney World was closed for two months at the start of the COVID pandemic, reopening on July 11. The theme park relaxed its face mask requirement for fully vaccinated guests of the theme park in most areas in mid-June.

Disney World still requires fully vaccinated park attendees to wear face coverings when using Disney transportation, including buses, monorails, and the Disney Skyliner.

Shares of Disney were trading at $173.07 as of 1:55 p.m. EDT on Tuesday, down 90 cents, or 0.52%.

The Walt Disney Company is expected to report strong first-quarter profits Tuesday. Reuters
