At all of 27 years old, last week Scarlett Johansson got her own star on the Hollywood Walk of Fame, cementing her place among Hollywood's immortal luminaries for as long as human beings still want to watch pretty people doing impossible things. In other words, she's permanent A-list, right?
Not exactly. For every Cary Grant or Mary Pickford with a star, there are five others you've probably never heard of. And yet there they are, their names emblazoned on a stretch of Hollywood sidewalk, vainly screaming their importance to the underside of tourists' Tevas. Will Scarlett be 2075's Irene Hervey? Or will her star become the same kind of mini-shrine as Marilyn Monroe's?
Before you answer, consider how much you know about the stars already there, from the obscure to the puzzling (you'd be surprised how many don't even belong to actual human beings). Or, better yet, take this quiz.
