The hard-working beat masters at Epic Rap Battles of History are going to the movies with their latest, “Steven Spielberg vs. Alfred Hitchcock.” And the filmmakers don’t pull any punches. “I produce cartoons and video games for all ages, you produce Jimmy Stewart making on of two faces,” the “Jurassic Park” director blasts. But Hitch isn’t going down without a fight: “Half your billions should go to John Williams, now brace yourself as I reveal my brilliance.” Sure, it’s billed as Spielberg against Hitchcock, but the feud is quickly co-opted by Quentin Tarantino, Stanley Kubrick and an appropriately shouty Michael Bay. The winner, though, is up to us viewers. Follow Ned Ehrbar on Twitter: @nedrick
