Each does colorful in their own sordid way, but letting Greenstreet do colorful lawful sounds like an extra-special treat.

It really is. He had such presence and so often it was in service of characters you couldn't trust as far as you could throw—you couldn't throw them—but he's just as believable as a character of principle. I wish I knew what he'd have looked like as a straight-up hero. He must have played one on stage sometime.
