"Actors who've given great performances in at least three diff. decades."
That's simple enough, right?
I'll start with the man who inspired this post: Ray Liotta in: 80s - Something Wild / 90s - Goodfellas / 00's - Narc
So, name the actor / actress and their great performances that have spanned at least three different decades. Also, if they've done it in four, five, or even six (??) different decades, put those down too.
