I've used both the actress name and pics (clothed of course, otherwise no one at the table woudl actually get around to playing) for NPC's/PCs before.
The best part is the look on a players face when they recognize the name or pic of the girl in question but either have trouble placing it, or are trying their best not to let on they know where it's from.

I also have a old print out of a few hundred native american names I pull out for the names of druids, elven hamlets, Serenity/Firefly ships, and the occasional hippie biker.
