Olympics 2018: Opening ceremony 'Peace in Motion' kicks off Pyeongchang Winter Games

The glittery spectacle featured a parade of nations and a whimsical storyline.

— -- The 23rd Olympic Winter Games officially kicked off in Pyeongchang, South Korea, today with a dazzling spectacle featuring a parade of participating nations and a whimsical storyline.

To fend off bitter cold and high winds in the area, spectators at the 35,000-seat temporary venue were provided with gear such as a raincoat, blanket and knitted hats as well as hand, feet and seat warmers. South Korea's state weather agency reported temperatures during the opening ceremony that reached 27 degrees Fahrenheit, with a wind chill below 16 degrees Fahrenheit.

Despite the cold, the audience appeared awed by the spectacle of 20,000 fireworks set off throughout the show, with some soaring nearly a mile high.

Hopeful tale of world peace

The opening ceremony, titled "Peace in Motion," emphasized its theme of peace by following the fairy-tale adventures of five imaginary children from Gangwon province with a cast of hundreds of other performers. The magical journey was performed in parts throughout the ceremony.

"The opening ceremony will weave together the narratives of five lovable protagonists from Gangwon province through cultural performances," Yang Jung-woong, executive producer of the opening ceremony, said at a Jan. 23 news conference in Pyeongchang. "The stage will unfold like a winter fairy tale depicting the children's adventure."

The storyline's five children -- Haenaroe, Ara, Puri, Bichae and Nuri -- travel through time to the past and future, learning about South Korea's history and culture. In the mythic world that the children explore, they first see a land of peace where nature and people live in harmony.

When the children enter the future world, where everyone and everything are connected, they realize the importance of working together for peace.

The children return to the present world as their journey comes to an end. They hold lit candles, passing the candlelight to a family who then shares it with other performers onstage.

About 1,000 residents of Gangwon province with lit candles came onstage to help form the glowing shape of a dove. An additional 35,000 people in the audience also held candles.

When the stage was illuminated with candlelight, four South Korean singers began singing John Lennon's "Imagine" as videos of 27 street musicians around the world singing the song were played.

The five children then released a faux dove, a symbol of peace, into the night sky.

The Rainbow Choir, a multicultural group of 75 children, sang South Korea's national anthem as the host country's flag was hoisted into the air.

A 'unification flag'

The athletes of the 2018 Winter Olympics marched into the Pyeongchang Olympic Stadium amid roaring applause and cheers. Erin Hamlin, the first U.S. athlete to win an Olympic medal in singles luge, was Team USA's flag bearer at the opening ceremony.

North and South Korea were last to enter the stadium. The teams marched together behind a "unification flag" carried by an athlete from each country, according to the International Olympic Committee.

Russia's national Olympic committee was barred from the 2018 Winter Olympics as punishment for its alleged state-sponsored coverup of doping by its athletes. But some individual Russian athletes will be allowed to participate in the games by competing under a neutral Olympic flag.

"You can only really enjoy your Olympic performance if you respect the rules and stay clean," International Olympic Committee President Thomas Bach said during his speech at the opening ceremony today. "In sport, we are all equal."

Eight South Korean athletes of winter sports carried the Olympic flag into the Pyeongchang Olympic Stadium, where it was hoisted and South Korean opera singer Sumi Hwang sung the Olympic anthem.

The Olympic Winter Games Pyeongchang 2018 Torch Relay arrived at its final destination at Olympic Stadium during the opening ceremony. The final torchbearers jogged up dozens of stairs to light the cauldron with the Olympic flame.

'Now is the time for Pyeongchang'

The 27.5-inch torch represents the altitude of Pyeongchang, which is nearly half a mile above sea level. Its white and gold tones are the main colors of the 2018 Winter Olympics Torch Relay.

South Korean actor and producer Song Seung-whan was the executive creative director of the opening ceremony.

The Pyeongchang Olympic Stadium will also host the closing ceremony for the 2018 Winter Olympics Feb. 25.

This is the second Olympics held in South Korea; Seoul was the host city for the Summer Olympics in 1988.

But as International Olympic Committee President Thomas Bach said at today's ceremony, these are "the first Olympic Games on snow and ice in the Republic of Korea."

"Now is the time for Pyeongchang," he said.
