Internet short films, while once a time-killing diversion for the YouTube set, have really come into their own. First, Joss Whedon’s Dr. Horrible’s Sing-Along Blog and now Prop 8: The Musical, with music by Marc Shaiman, and featuring Jack Black as Jesus; John C. Reilly, Allison Janney, Sarah Chalke, Kathy Najimy, and Craig Robinson as the Religious Right; Maya Rudolph, Andy Richter, and Margaret Cho as the Gay Chorus; and Neil Patrick Harris as… Neil Patrick Harris. This is brilliant stuff. Oh, and for those who don’t know, Prop 8 is the California legislation that declares the only constitutional marriage is one between a man and a woman, overriding the previous state Supreme Court ruling that deemed gay marriage as legal and binding. Who says entertainment can’t be educational?
