You have to implicate the audience. They’ve got to squirm, not just over what happens, but because they did nothing about it. They had all the knowledge – this guy was not to be trusted – and they just sat there. People have jumped onstage to stop Iago, wrestled him to the ground. One actor in the 19th century was killed in the part, shot by an audience member. I’m glad that didn’t happen. Maybe I just wasn’t good enough.
