Trivia: The horse heart that Daenerys eats was actually made of gelatin, and genuinely tasted dreadful - her physical revulsion at eating it is real. It had dyed pasta to simulate veins, and was injected with fake sugary blood, which attracted flies. The blood was so sticky and ended up covering Emilia Clarke to such an extent that after filming it glued her to the toilet seat.
