While it’s not entirely out of the ordinary for someone to pass away at the age of 70, it can still be a pretty sad event and my sympathies go out to his family. We have indeed lost a great actor.
If you want to see just how great we’re talking about here, this video of him acting at a sequence from Who Framed Roger Rabbit with nothing but blue screen around him should give you a pretty good idea of what he was capable of. I just don’t know how he did it.
