Rupert played Luciana in an all-male production of The Comedy of Errors at the Shakespeare Festival Neuss in Germany. I assume it was this production in July 2004, as we’ve heard separately that he was in a production of this play for Wild Thyme Productions in 2004. According to his CV, the director was Stephen Jameson.
The all-male cast wouldn’t have helped with all the mistaken identities! Seriously, though, I see they also did an all-female Hamlet, which must have been extraordinary.
