What is Robert Downey Jr.'s net worth? Simu Liu raves about his "convoy of trailers" during the shooting of Avengers: Doomsday

Simu Liu recently offered fans a glimpse into the making of Avengers: Doomsday, revealing just how expansive Robert Downey Jr.’s on-set setup was during filming. In an interview with Collider published on Monday, December 29, Liu described Downey Jr.’s production footprint as so massive that it became a landmark of its own on set.

Liu explained that Downey Jr.’s setup was not just a single trailer but an entire cluster of trailers that stood apart from the rest of the base camp.

“Downey famously has this convoy of trailers and this whole area in base camp that we affectionately called Downey Land,” Liu said.

Robert Downey Jr., who has a reported net worth of $300 million according to Celebrity Net Worth, was best known for his iconic role as Iron Man in the Marvel Cinematic Universe.

However, he returned to the franchise as Dr. Doom, the main villain, in Avengers: Doomsday. Liu reprised his role as Shang-Chi in the film.

Simu Liu then recalled his first time being invited into Downey Jr.’s personal space. He noted that the experience immediately reflected the actor’s self-aware humor and larger-than-life personality.

“And I remember getting invited to Downey Land for the first time and just showing up in this tent, and it’s all this beautiful Andy Warhol-esque artwork, except all the characters are Downey. I mean, he was so self-aware,” he explained.

During the aforementioned interview with Collider, Simu Liu also described what a visit to Robert Downey Jr.’s so-called “Downey Land” felt like to him.

Liu recalled that he initially arrived with his own packed set lunch, completely unaware that Downey Land operated with its own private chefs and a full catering service.

“So, he greeted me, and then I didn’t realize that Downey Land has its own chefs, but I had brought my set lunch, and he was like, ‘Oh, no, no, no. We don’t do that here,’” Liu said.

After that moment, Liu described how a full buffet was laid out by the chefs, prompting him to quietly put his lunch away as people casually passed through the space.

“The chefs had come and laid out this full buffet, and I was like, ‘Oh, I’ll put this away.’ And then just the people walking through, I was like, ‘I cannot believe I’m having lunch with these people,’” he explained, emphasizing how surreal the situation felt.

Beyond the spectacle of the setting itself, Liu said the experience with Robert Downey Jr. forced him to mentally recalibrate.

He explained that it was important for him to suppress his inner fan, stressing that he deliberately “put that fan side away” and mentally reframed himself as a professional peer rather than an admirer.

According to Liu, allowing himself to be starstruck in that moment would have made it harder to focus on the work at hand.

He described how he consciously compartmentalized his awe, repeatedly reminding himself that he had “a job to do” and that maintaining professionalism was essential. He explained:

“I’m not a fan. I’m a coworker. As ridiculous as that sounds, or as ridiculous as it sounded to me at the time, I was like, ‘No. I have to treat these people as my equals, even though I’m literally like a little boy right now.’”

Additionally, both actors are part of the sprawling Avengers: Doomsday ensemble, which has brought together longtime Marvel figures, including Chris Hemsworth, Florence Pugh, and Tom Hiddleston.

The film is also set to feature returning X-Men actors, like James Marsden, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, etc. The cast will be further rounded out by newer MCU additions, including Pedro Pascal, Channing Tatum, Vanessa Kirby, and several others.
