Comic Book Resources asked me for comment about the $30,000 investment:
The Dark Knight—the title of which is a nickname coined by Bill Finger, the main villain of which debuted in a story written by Bill Finger, the legacy of which is that it is one of the highest-grossing and most critically praised films of all time—has many hundreds of names in its credits, but none are Bill Finger. None of those people would have had that job if not for Bill Finger. This Walk of Fame star is yet another instance of Kane receiving recognition I don't feel he deserves...unless Finger gets the same.
My initial tweet about this was a bit snarkier:
Bob Kane getting star on Hollywood Walk of Fame. Now people can step on him as he stepped on Bill Finger.
