I sympathize with the zombies and am not even sure they are villains. To me they are this earth-changing thing. God or the devil changed the rules, and dead people are not staying dead. ↗
Things were easier for the old novelists who saw people all of a piece. Speaking generally, their heroes were good through and through, their villains wholly bad. ↗
I never play a villain that I don't have something I can either do or say so the audience sees there is something redeemable about them. In other words, I don't want to do evil for evil's sake. I don't want to do Jason slasher movies. There's no point in that. ↗
