Yes, and look at all the warnings he had during the making of this film and prior to that as well. It makes you think that he certainly could have survived if he had attended to at least even one warning.
I haven't seen the film. What do you make of that photo of him lying on the floor with his eyes opened and people attending to him? Was that a scene and before they did it, he had the sweat wiped off or something? He looks AWFUL - like he'd already had a heart attack. I know the stories differ but everyone seems to agree that at one point, he went to his dressing room. I wonder about it and would love your insight.
