A reading of a fan-written spec script for Ghostbusters 3 will be held in Hollywood tomorrow night. Admission is free. Now, that sounds basically like something that would happen any given Sunday at your college, right? No big deal? Well, this particular reading will feature some of the nation's top voice talent in a one-night-only event. Futurama alumni Phil LaMarr and Maurice LaMarche (with whom ComicBook.com recently spoke--check it out!) will head up an all-star cast. LaMarche played Egon Spengler on the popular '80s/'90s TV series The Real Ghostbusters, which spun off a comic book series from NOW. The reading will take place tonight at the Los Angeles Film School Theater; you can see more details on the poster at left.
