Testament vocalist Chuck Billy has recorded some "additional voices" for a new episode of Marvel's What If…? animated anthology. Billy will be featured in the episode What If… Doctor Strange Lost His Heart Instead Of His Hands?, which is available now on Disney+.
Billy told The Jasta Show that the producer of the episode is a Testament fan, and that recording the lines was a great time.
"That was an experience, because the producer was actually a Testament fan, and he actually [sought] me out. And it was so great and made it so easy. I'd never done that for a movie and action part. So when you go in there, they got this — it's like a barricade you stand in front of, a padded barricade, and there's the screen and the microphone. So you can use the barricade to kind of move and get into character. And I was doing a lot of flying and yelling and fighting and shit like that.
"So it was great, 'cause the producer was, like, 'All right, so on this part, do the 'Demonic' voice.' And I'm, like, 'Oh, okay.' So I'd do that. 'Okay, on this one, do the 'Practice What You Preach' voice.' It was so cool that he could give me direction like that. It was the easiest thing. And I had a blast. And it was right the middle of COVID."
