This project is in desperate need of a few extras here and there. It would be fantastic if we had some different voices to add into the mix when there's a general discussion going on or if I need some extra voices for an atmospheric crowd. Extra voices may not have many lines in the script but will be pivotal to the listening quality.  That being said, you may have to be confident in your ability to improvise as all your lines may not always be "written out" per se.
