So it took me a second to catch the whole Rupert as a horse/equus reference ... it's like one in the morning here ...

you're sly Ems ...
But what would ever posses him to dress up like a horse?

Our dear Rupert is displaying his true acting talent. Sure Dan will bare it all for a play, but Rupert isn't just content to act any old human part ... he'll play the horse ... now that's acting!
Rupert is too cute ... yay ... and evil Ru? I can't wait ...

but I'd still have cast him as Jimmy Olsen in my Superman movie ... Dan can be one of Lex's minions ...

Hermione as Lois ... I can already see the love quadrangle ...
