Damn, this is terrible. Though, truthfully not completely surprising given he had pancreatic cancer, which is one of the worst cancers out there and in most cases a diagnosis is essentially a death sentence. Still, considering his diagnosis was in June 2015, to have lasted a year and a half after being diagnosed with it is quite an accomplishment. Shit, I was only just thinking about John Hurt the other day and wondering how he was doing. This is not the news I wanted.
Still, the man's contributions to cinema are extensive and well known. And while the War Doctor has been a point of contention among fandom, I think we all have agreed that whatever issues the existence of the character have created, John Hurt provided an excellent performance with the role, and if for no other reason the existence of the War Doctor is justified as it gave us the opportunity for John Hurt to be the Doctor.
