Hi! Just so you know, we only use the performer box for those who have been established as the main performer for an extended period of time. Anything else goes in the Casting History section of the page. Thanks!
Hi! IMDB credits him as 'Human Walter', and for the descriptions some people have given of the character it seems he is one of the best kept secret of the movie.
Thanks for your response! Unfortunately, we don't consider IMDb a reliable source, so that will probably be removed for now. The movie comes out in over a week, so by then, all will be answered =D
