Marvel Cinematic Universe fans likely remember that while WandaVision was on the air, co-lead Paul Bettany had a bit of fun trolling fans, who were already picking apart episodes every week.
Bettany would later confirm this was the case.
During an interview, Bettany explained that he got to work with someone on the show that he’d “longed to work with all of my life” and said that he and the person had “extraordinary” chemistry.
Many fans assumed he was referring to a totally new MCU character but, after the show unveiled a white variation of Vision (also played by Bettany), many began to wonder if that was the cameo the actor was referring to.
