While unable to provide details, Bethany did write about her casting on her Facebook page:
“It is genuinely the greatest job I could ever have imagined getting. Everything about it is magical. I’m enjoying every day of filming and cherishing it, because you never know if you’ll ever get to do anything like this again. I only hope that I do the role and the show justice, and that you all enjoy it. For me it’s the gig of a lifetime.”
Episode 9 is the “found footage” story, which will be done entirely in ersatz cell phone videos.
