Johnny?? Johnny!!! Noooooooooooo!!!!!

It occurred to me while watching V for Vendetta, which I found to be surprisingly excellent, why doesn't anyone ever try CPR in movies? The "dying in the arms after saying something incredibly dramatic" thing has been done so many times, but why doesn't anyone ever make an effort to keep said dying person alive? A few pumps on the chest, some mouth to mouth, for fuck's sake make an effort!
