Disney's mega-hit Frozen has become a global phenomenon with its abundant business grossing over nearly $1 billion worldwide, as the demand for all things that has to do with the film's kingdom of Arendelle continues to skyrocket.

Especially, the dresses based on the successful movie are in great demand: a version of Queen Elsa's icy blue dress, which its original in-store retail price is $149.95, is selling for as much as $1,000 on eBay. Similarly, a cheaper version of the limited-edition garment, originally sold for $20 in Disney stores last November, is fetching somewhere between $150 and $350.

Besides the dresses, the limited-edition dolls of the queen and her sister Anna, which retailed for $99.95, were all sold out in just 45 minutes after launching on disneystore.com in January. The Frozen storybook app tops the kid's category in more than 100 countries, while the book rendition is on the New York Times bestseller list.

"We're thrilled that audiences formed an instant connection with the characters," said Disney spokeswoman Margita Thompson.

Disney, the world's biggest lincensing company, has taken unusual steps to capitalize on the film's success, such as airlifting inventory from overseas to speed up the availability of Frozen products in more than 200 Disney Stores in the U.S.

In addition, Jakks Pacific is set to release a singing interactive Elsa doll this fall and already designing Halloween costumes. "Frozen is turning into an evergreen property that we'll nurture with Disney for a very long time," said co-founder Stephen Berman, who believes that the license could become "one of the best properties we've ever had."
