Progress is moving along on Invincible‘s second season as Steven Yeun is officially back in the recording booth working on new dialogue. Footage of the actor back at it was posted to Twitter, providing a small tease at Yeun’s return as the voice of Mark Grayson. We don’t get to hear Yeun in character as Mark, though he expresses his excitement at getting to make more Invincible before having some awkward banter about when he should or shouldn’t have the video cut off.
