I too am not into "celebrities." Celebrities often lead negative lifestyles and are all into themselves. They often live miserable lives underneath the miles and strutting of their stuff. They are very poor role models and their talents are very limited.
I like the term someone used "Celebrated actor." In that vein, Meryl Streep is someone to celebrate. What a brilliant actress.
Another fave is Anthony Hopkins. Those are my top two.
Others on my list would be Tom Hanks, Clint Eastwood, Ron Howard, Glen Close, Kevin Costner, Ed Harris to name a few. Quality actors and directors. Their private lives are private and from what I can see, they are very diligent about growing in their craft and show immense creativity.
