Why are we so obsessed with celebrity? Obviously it makes sense to admire a talented person, and if that person finds fans all over the world, then they've earned that spotlight. But beyond that, why do we care if Brad Pitt gets a divorce or if a troublesome starlet goes to jail? Why are there TV shows who employ photographers to prowl airports and emergency rooms so that maybe we can get a new "candid" photo of a popular actor? That's a question for the sociologists, the psychiatrists, and (in this case) the filmmakers. Antiviral, the stark and disturbing debut feature from Brandon Cronenberg, offers a science fiction concept, a film noir vibe, and a horror flick soul, and if it seems like the writer/director is starting off on the same thematic foot as his dad, that's because he is.
