Also a lawyer, and the Middler case is apparently not understood so narrowly. The possible chilling effect on employability of actors who happen to look or sound just like already famous actors rankled me, too, and I really got into it with my entertainment law professor (who has had some quite high profile clients). His advice in no uncertain terms was basically “Sorry to those actors, but if you try to get away with hiring one of them knowing they’re likely to be confused with someone more famous, you’re stupid.”
