Ben Kingsley will reprise his role as Trevor Slattery in the upcoming "Wonder Man" series. In "Iron Man 3," Trevor Slattery was hired to portray the Mandarin; Slattery later escaped imprisonment in "Shang-Chi and the Legend of the Ten Rings." Now, it appears that Ben Kingsley will continue acting in the MCU. Wonder Man has both been a hero and a villain in the comics, so it will be exciting to see how Trevor Slattery will interact with this character. The series will probably be released around late 2023 or early 2024.
