This is an open role for anybody! Most likely, as long as your mic is good quality, you're already in somehow! There are some roles like Oolong and Marron that I felt didn't need to be included on here because I think those roles can easily be mastered by the VA's who will be in the cast, but if you think you have what it takes for the roles that weren't listed, go for it! Just make sure you're mentioning what role it is in the recording. There will be some point where there'll be random citizens on screen or something else along the lines of that. The only requirement is that you have a decent quality mic.
