The cast and crew attended a ceremony to mark the start of filming at China Movie Metropolis, a studio complex in Qingdao, Shandong province, which also hosted production of the previous two entries.

Producer Fu Ruoqing, chairman of China Film Group, director Frant Gwo, and lead actor Wu Jing attended the ceremony, where they announced the surprise casting of comedian Shen Teng.

Shen brought his signature humor to the launch, saying he was honored to join the team. "I'll do my best in this role and make sure director Frant Gwo gets enough rest, while ensuring I get enough rest myself," he joked.

Wu shared his excitement about working with Shen: "I'm so hyped to have fun with Shen Teng on the 'Wandering Earth' ride. Maybe we can have a switch. Hope I get more comedy scenes while he does more action — can't wait to see him throw a punch!"

Shen and Wu are two of the biggest stars in Chinese cinema. Films starring Shen have grossed a total of 36.98 billion yuan ($5 billion) at the box office, making him the highest-grossing actor in China. Wu ranks a close second, with his films earning 34.71 billion yuan. The long-awaited collaboration between the two actors will take place in this project.

At the launch of "The Wandering Earth 3," the production team unveiled WEi, a proprietary AI assistant powered by DeepSeek R1 and supported by NVIDIA and ByteDance's Volcano Engine.

The tool, which is designed to emulate the franchise's AI character MOSS, provides instant access to scripts, concept art and professional references. The production team said the tool integrates AI with film production to help advance China's sci-fi industry and explore new creative possibilities.

The production will also partner with leading Chinese technology firms to leverage advanced support, aiming to set a new benchmark in set construction and visual effects.

Producer Fu expressed gratitude to the director and core creative team for overcoming challenges over the past decade since the first film. He pledged to continue supporting the team as they pursue the sci-fi vision of the "Wandering Earth" franchise and work to ensure its continued growth and legacy.

Another franchise star, Hong Kong actor Andy Lau, sent a congratulatory video for the production launch, saying, "I can't wait to rejoin the cast and begin filming."

Screenwriting adviser Wang Hongwei said the script for "The Wandering Earth 3" was 80% complete.

"When working on a groundbreaking franchise like this, we all feel reluctant to put down our pens," Wang said, adding that the team aims to create the most satisfying conclusion possible for the final installment.

The film is written by Gwo, Gong Ge'er and Ye Ruchang. Gwo previously said the script underwent nine revisions by the end of last year, with the team surveying over 1,000 young people to better engage younger audiences. The story will serve as a direct sequel to the first film, exploring humanity's struggle for survival during Earth's 2,500-year cosmic odyssey to a new solar system.

"Innovation must be everything — we have to find ways to make it happen," Gwo said. "We want to give audiences something they've never seen in any film before. We're raising production standards far above the first two movies to move and amaze every audience member who's been supporting us."

The "Wandering Earth" franchise has maintained its strong audience appeal with consistent box office success. The original 2019 film earned 4.69 billion yuan domestically, while the 2023 prequel grossed 4.03 billion yuan. The series' final installment, "The Wandering Earth 3," will be released in two parts, with the first part scheduled to premiere in China during the 2027 Spring Festival season.
