Simu Liu Reveals What It’s Like Working with Robert Downey Jr. in Avengers: Doomsday [Exclusive] (2026)

The 'Avengers: Doomsday' Star's Insightful Take on Working with Robert Downey Jr. [Exclusive]

'Avengers: Doomsday' Star Simu Liu Shares His Experience Working with Robert Downey Jr.

In a recent interview with Collider, Simu Liu, the star of 'Avengers: Doomsday', opened up about his experience working alongside Robert Downey Jr. on the Marvel Cinematic Universe (MCU) film. Liu, who plays Shang-Chi in the MCU, expressed his excitement and awe at finally sharing the screen with one of the franchise's pioneers, Robert Downey Jr., who portrays Doctor Doom in the film.

Liu's enthusiasm was palpable as he described the moment he met Downey Jr. for the first time. He felt a sense of disbelief and excitement, knowing that he was in the presence of a Hollywood legend. Despite his years of experience in the industry, Liu admitted that there were still pinch-me moments along the way, especially when he realized the magnitude of the opportunity.

However, Liu was also acutely aware of the mental shift required to perform his role. He emphasized the importance of compartmentalizing his fan side and treating his co-stars as equals, even though he was a fan himself. This mindset shift was crucial to his performance and allowed him to fully immerse himself in the character.

One of the most memorable aspects of the experience was Downey Jr.'s set area, affectionately known as 'Downey Land'. Liu was invited to Downey Land, where he was greeted by a convoy of trailers and a beautiful Andy Warhol-esque artwork featuring Downey Jr. as the central character. The area was complete with its own chefs and special guests, adding to the surreal nature of the experience.

Despite the spectacle, Liu was most struck by the normalcy underneath it all. He enjoyed the everyday conversations and interactions with his co-stars, even when they were in full costume. These moments, he believes, are priceless and irreplaceable memories that will stay with him forever.

As 'Avengers: Doomsday' prepares to reset the MCU's hierarchy and usher in a new era, Liu's reflections offer a glimpse into the quiet, human moments behind the spectacle. Fans will have to wait until December 2026 to witness the film's spectacle, but Liu's insights provide a unique perspective on the making of the MCU's next massive crossover.
