Before making a significant impact in the Marvel Cinematic Universe (MCU), Simu Liu had a brief but notable role in the critically acclaimed series The Expanse. His performance as Paolo Mayer, a lieutenant in the Martian Marine Corps, occurred three years prior to his breakout role in Shang-Chi and the Legend of the Ten Rings, which catapulted him to mainstream fame. Although Liu’s filmography is not extensive compared to some of his MCU peers, he has established a commendable presence in both film and television. Furthermore, Liu recently gained attention for his portrayal of Ken in the highly anticipated film Barbie, directed by Greta Gerwig.
The Expanse, based on the acclaimed novels by James S.A. Corey, experienced a tumultuous journey following an initial cancellation by SyFy after three seasons. However, the show’s dedicated fanbase and critical acclaim ultimately led to its revival on Amazon Prime Video, where it continued for three successful seasons. Liu made his debut in this celebrated series during its third season, contributing to a cast renowned for its diversity and star power.
