I don't have a model for valuing domain names, but I will offer some general ideas.
My first thought was celebrities. Best-dressed/Worst-dressed lists (calling Mr. Blackwell...).
However, Hollywood is a place, so any location-specific list might apply, such as classifieds, job listings, movie listings, restaurant listings, etc.
Hollywood also denotes a sense of glamour in some circles, so you might apply that angle to advertising certain kinds of products.
Hope this helps.
