Joseph's guest role as Captain Branson in the Showtime series Penny Dreadful will be seen in episode 5 'Closer Than Sisters', and not episode 6 as I mistakenly posted on here. Apologies, I misread an email. The good news is that his episode will air on Showtime on June 8th at 8pm. Even better news - 2 new hi-res stills of Joseph in character have been shared on here. Thanks to Lorna for spotting the photos.
