Well there are the obvious ones: USC, Columbia, and UCLA.
As for more regional schools, I'd say
NY: Fordham and Cardozo (One of my old professors is a very successful lawyer for the Tribeca Film Center/DeNiro and she graduated from Cardozo.)
LA (I'm not too sure on LA ones... but I think): Loyola, Pepperdine, and Southwestern
But don't trust me on the LA ones. That's just what I've heard through the grapevine.
I'd recommend, if anything, looking into major entertainment firms in LA and NY and checking out where their present lawyers graduated from or where they do OCIs.
USC really is the best one though.
