In a YouTube video posted by David Finch titled “Drawing Omni Man and a conversation with ROBERT KIRKMAN,” Kirkman revealed who Yeun will be portraying in the upcoming MCU film. The Beef actor was previously rumored to be playing Bob Reynolds/the Sentry in Thunderbolts, which Kirkman’s comments then confirm.
“My good friend Steven Yeun is playing the Sentry in a movie,” he said. “He called me, he went in for a costume fitting.
“I don’t think this is a spoiler or anything that’ll get anybody in trouble,” Kirkman continued. “I don’t know, maybe, we’ll see. I don’t care, I don’t work for Marvel, what are they going to do to me? He said, ‘I just came back from a costume fitting for the Sentry. I guess I only do superheroes that are yellow and blue.’ He said he was at the costume fitting and was like, ‘Oh crap, I forgot Invincible is yellow and blue.’”
