Nicholas Zebrun mentions that he was in a play directed by Nikki Hinson. The play in question - "Cinderella Waltz" - was Hinson's first directorial gig and introduced Mr. Zebrun to Sarah Guyote-Sebastian, who later became a frequent collaborator. David Sowden was prop manager for it.
So far, the only episode of the show to be directed by David Sowden. He put together the guest roster and encouraged Nicholas Zebrun to do the episode poolside as a way to break the monotony of the indoor setting the show had adopted.
