Some brainstorming with good friends yielded this:
George Clooney ?
Henry Rollins definitely not INTP rather ISTP. He is way too physical for INTP!
Nicolas Gage rather E than I
Elijah Wood rather E than I
Simon Cowell rather ENTJ than ISTP, ISTP's are not as vain as him and he has intuition with his business!
Richard Gere definitely INFx
Russell Crowe definitely not ISTJ, rather ISTP
George Lucas definitely N
Dr. Phil definitely ENFJ
George Clooney probably artisan or idealist
I was under the impression that Bob Dylan was an ISFP.
He definitely is. He fits ISFP to a T... although some of his lyrics and some of the thoughts from his book Chronicles indicate he may be a solid mix of S and N but with a preference for S. He'd say stuff like "I would take things for what they were, not adding anything" (not exact words but same idea) which is a very S thing to say, but some of his songs seem to be N, like Blowin' in the Wind. I don't see how he is T or J, really, especially T.
