In reply to Tom Last:
Yes, I was surprised, and this is a real loss (as opposed to long-retired folk in their 90s); he had more DECADES of performances in him.
What was really stunning about him was that his physicality never seemed to restrict his range; he was very versatile across comedy, drama, indie, arthouse and blockbuster etc.
Coincidentally I recently watched The Talented Mr. Ripley for the first time and although his role is minor, and I wouldn't say he "steals" any scenes let alone the film, the scenes with him are by far the most edgy - and that was down to his performance, not the writing or directing.
He'll be missed.
