I have always been amazed at extras on TV shows. I love the way they overact. I have just been watching an episode of Stargate Atlantis and as the camera was doing a pan across the set, in the background you could see a man in a white coat (a doctor presumably) talking- or miming- to a 'soldier' with a large bandage over his head with big red stain on it. And as the camera panned across, the wounded soldier pointed (in an exaggerated fashion) to his blood stained bandage, while the doctor nodded. Now I know I read too much into things and this was only supposed to background action. But how do you expect me to believe that there was a conversation occurring where the patient points at a bloody bandage? What on earth could the doctor have asked? "Can you tell me where you were hit?" For crying out loud there is a big bandage there with a huge blood stain! Where do you think he was bloody well hit? My god no wonder the Stargate crew are always in trouble if the medical staff are so inept that they can't even see where an injury is on a man with a bandage!
