Oh yes, two of my novel characters were heavily inspired by real actors. And if I had a time machine to pick them up during times where they better match my characters' ages for them to play I'd use it for sure.
I pretty quickly came up with Valon's character after I examined some of Stephen Lang's roles.

As for Schuler, I had a hard time nailing down his character until I saw Sam Elliott in Road House.

And a bit later on, after rewatching Death Note, I realized that the English VA for Ryuk, Brian Drummond, would be perfect for Anax.
