Park Seo-joon, best known for his roles in Itaewon Class and Parasite, is rumored to be portraying Captain Marvel’s (Brie Larson) husband, Prince Yan, in the upcoming film The Marvels. Rumors of Seo-joon’s casting in the Marvel Cinematic Universe (MCU) first arose in the summer of 2021 when Daum reported that he had been cast in the Captain Marvel sequel. By September 2021, his talent agency confirmed that his casting in The Marvels was official. However, nearly a year after he was first rumored to be appearing in The Marvels, his role has remained undisclosed.

Fans have theorized about who the South Korean actor might be portraying in the MCU. Initially, the theories suggested that Seo-joon would be portraying Noh-Varr in The Marvels. In the comics, Noh-Varr is a soldier serving under the Kree empire in an alternate universe. His powers were further enhanced by the fact that he had altered his DNA with insect genes, making him half-man and half-cockroach. During a mission, his ship was destroyed as he and his crew flew over Earth 616. After the crash landing in New Jersey, Noh-Varr played a prominent role in Secret Invasion which is set to become a Disney+ TV series in 2023.
