Alien
Spaceballs
Indiana Jones and The Kingdom of The Crystal Skull
Recount

Too many to mention. He's been superb in all his movies and never disappoints.

1984
Alien
V for Vendetta
Midnight Express
The Elephant Man

For me he'll always be Winston Smith from 1984, but I also love him as Max in Midnight Express, John Merrick in The Elephant Man, Kane in Alien and James Graham in Rob Roy.

The Elephant Man (1980) . John Merrick
All the Little Animals (1998).Mr. Summers
Hellboy (2004) . Trevor "Broom" Bruttenholm
Way too many great roles to choose from. I picked 3 that probably won't get a lot of mention from others but gave me great joy.
The truth of life has been revealed.

I'm a major "parody lover" so my favorite role of his is when he parodied himself in Spaceballs. When the alien cracked out of his chest he said "Oh no, not again!"
He will be missed.

Let me just say that he improved every movie he was in - rare Star quality and a great human being
"I am not an animal " - heartbreaking

Max from midnight express and Kane in Alien

Loved him as the voice of the Great Dragon in Merlin even now I can hear him saying MERRRRRRRRRRRRRLIN!!!

The Marquis of Montrose in "Rob Roy".

Peter Strelzyk in Disney's 'Night Crossing', based on the true story of two families escaping from East Germany in a hot-air balloon.

Caligula in I Claudius
Kane in Alien
Quentin Crisp in the The Naked Civil Servant
Joseph Merrick in The Elephant Man
Control Tinker,Tailor,Soldier,Spy
Trevor "Broom" Brutten in the Hellboy movies
Winston in 1984 (it's no small feat not to get upstaged by Richard Burton)

OMG, this is so hard to answer. He was so good in so many things.
But the one that's uppermost in my mind right now is
Control
, in 'Tinker, Tailor, Soldier, Spy.'

Caligula in I Claudius & Midnight Express prisoner & Kane in Alien were my favourites.

Caligula in I, Claudius.
Winston Smith in Nineteen Eighty-four.
Kane in Alien.
Chancellor Adam Sutler in V for Vendetta.
Joseph Merrick in The Elephant Man.
What has he ever done that isn't to love? Every production he was ever in was elevated by his presence.

Whenever he appeared in a movie or TV show it immediately improved. For me, he'll always be The Storyteller. He had a very distinct acting voice. I will miss him.
. . . The Bones tell me nothing.

Either The War Doctor or Chancellor Sutler in V for Vendetta

Nobody suffered more exquisitely on screen than John Hurt. Damn!

Wow Mr. H! Only you could see it and express it like this, in a few simple words.
I love The Naked Civil Servant. It is a little gem of a movie, yet for me, it also has an overwhelming current of sadness running through it. Crisp had a life, yet at the same time, he had no life, and his tenacity, intelligence and humor gave him the tools in which to survive.
Don't eat the whole ones!Those are for the guests.

Well, I haven't yet seen "The Naked Civil Servant" (and I really want to. I think Quentin Crisp is a true hero.) Max from "Midnight Express" would be my favorite, followed by Kerwin in "Partners" (which I liked a lot more than most people) then Kane from "Alien". John Hurt was one of my favorite actors. Nobody suffered more exquisitely on screen than John Hurt. Damn!
