The possible series that the news channel THR confirmed was in the works during June is centered on one of Marvel's most enduring characters, Simon Williams/Wunderman.
The character was first introduced by 1964's Marvel Comics, initially as the villain, but then changed to a hero character during the 70s.
Wonder Man was a founding part of the West Coast Avengers in the 1980s, while Williams worked as a stuntman and actor.
Wonder Man will be Kingsley's fourth appearance as a character in his role in the MCU following his scene-stealing turn of 2013.
The director of the latter, Destin Daniel Cretton, is co-creator as well as the executive producer for Wonder Man, alongside director and author Andrew Guest ( Brooklyn Nine-Nine).
Kingsley's Slattery is an actor who was hired to play the role of the villain The Mandarin in Iron Man 3.
Then, he was as a character in 2014's Marvel movie "All Hail King" in which the character was released from prison by one of the Ten Rings organization before turning back for Shang-Chi.
