Australia’s Thunder From Down Under, the longest-running and highest-grossing male revue in the history of Las Vegas, will continue to be the “Ultimate Girls Night Outback” thanks to a 10-year extension and the partnership with SPI Entertainment and MGM Resorts International. The partnership will begin this summer with the opening of Thunderland in July and the $6 million renovation of its current showroom and show.

“We could not be more thrilled to announce this incredible partnership with MGM Resorts/Excalibur,” said SPI Entertainment Founder and CEO, Adam Steck in a statement. “We have the most high-energy crowds in all of Las Vegas — and we cannot wait to bring that excitement to the next level as they experience Thunderland at the Excalibur for the next 10 years and beyond. I am proud that we have pioneered the genre — and moreover, that we continue to set a new standard for it, as audiences will see with this next evolution of the show.”

Billy Cross, show creator and CEO of Cross Promotions International, said in a statement, “This is an incredibly exciting time for our brand. What we are bringing to life with Thunderland is going to be a game-changer in entertainment. We have listened to what our audience wants — and although the core fundamentals and brand attributes will stay the same, we are delivering a new and completely elevated experience.”

Thunderland will transport guests even further into their fantasies. The show goes all out with three performance stages within the showroom in addition to the main stage, as well as other performance areas throughout the venue. The fully immersive experience will include state-of-the-art sound and lighting, special effects, and high-resolution, movable LED screens.

Thunderland will also increase the venue capacity from 375 to 425 and add the new “Thunder Lounge” with programming before and after the show.  The performance schedule will also be expanded with new 11 p.m. shows added on Thursdays and Sundays.

To accommodate the many more fantasies, Thunderland’s cast size will also expand. As will the costumes and dance routines.

James Trudeau, Vice President, Entertainment Booking for MGM Resorts International, said in a statement, “Adam and the SPI team have done a tremendous job over the years of producing some of the most entertaining shows on The Strip.  We look forward to our extended partnership with SPI and are excited to deliver our castle guests a new entertainment experience in the Thunderland showroom.”
