Invincible's Gillian Jacobs Explains The Hardest Part Voice Acting For Her

On top of the fact that Gillian Jacobs herself finds this particular aspect of voice acting to be creatively challenging, her comments also make it clear that making these noises can be physically exhausting as well.

According to Jacobs, the team actually saves all of these "battle noises" for the end of each recording session since they can exhaust your voice so much. Despite how blatantly difficult this part of the job might be, Jacobs went on to describe just how much she loves her role in "Invincible," saying: "The scenes themselves I love doing. I love getting to be a part of that show."

Although it certainly seems like crafting every single grunt, sigh, gasp, or battle cry for an entire season's worth of action television might be too exhausting for some, it's clear that Gillian Jacobs loves the show enough to stick with it — even if she does feel a little silly in the recording booth.
