LOS ANGELES, CA.- Julien’s Auctions announced today the Sci-Fi auction event of the season “Kaiju King: The Sompote Sands Legacy Collection” an exclusive live auction taking place Wednesday, September 23, 2026 in Los Angeles and online at juliensauctions.com.

A remarkable archive of over 300 original film artifacts and memorabilia direct from the estate of the legendary filmmaker and tokusatsu (special effects) visionary Sompote Sands, will be offered at auction for the first time in history, spotlighting his work in the Ultraman universe and providing fans and collectors a once-in-a-lifetime opportunity to own a piece of the global pop culture phenomenon. The collection, amassed over five decades by the founder of Chaiyo Productions and displayed at his personally curated museum ‘Sompote House’ in Thailand, includes production used suits, monster miniatures, props, scripts, vintage hero figures, toys, original artwork and behind-the-scenes treasures.

Artifacts from his early career and film apprenticeship in Japan including 1962’s King Kong vs. Godzilla from production scripts, photographs, film equipment to posters and more will also be highlighted.

Sompote Sands was Thailand’s pioneering special-effects director and producer in the 1970s-1980s, revered for bringing giant heroes and mythological creatures to the screen in Southeast Asia. He helmed the iconic films Hanuman vs. 7 Ultraman, Hanuman and the 5 Kamen Riders, the superhero/kaiju film Jumborg Ace & Giant and more, delivering his brilliant craft of practical effects and miniatures to audiences in his homeland of Thailand.

The forthcoming sale marks the first time Sompote Sands’ personal production archive from his company Chaiyo Productions, representing his work and the culturally significant era of his time, will be available to the public. This auction joins all the excitement and events taking place around the world in celebration of the 60th anniversary of Ultraman. Since the premiere of Ultraman in 1966 this cornerstone of Japanese pop culture has become an international phenomenon, generating a billion-dollar merchandising industry and spawning numerous sequels, spin-offs, and tributes worldwide and influencing anime, manga and the modern era of sci-fi filmmaking with blockbusters Power Rangers, Pacific Rim, and Ready Player One among others.

“Sompote Sands was Southeast Asia’s Steven Spielberg, a pioneer in science fiction filmmaking whose films blending Thai folklore storytelling and practical special effects wizardry filled audiences with cinematic wonder,” said Catherine Williamson, Managing Director of Entertainment, Julien’s Auctions. “This exceptional auction of artifacts from his film career and notably his cinematic contributions to the Ultraman franchise will not only excite fans and collectors of the worldwide cultural icon but also the booming global toy collectibles market with Sands’ collection of rare film props, action figures and movie memorabilia from the cross-cultural Golden Age of Southeast Asian sci-fi film productions coming to auction for the first time.”
