I was walking around Wexford at night just an hour ago and saw a circle of spot lights radiating out from some point to the south, lighting up the clouds. I saw them change angle once, and saw one of them flicker as if someone had stepped in front of it. I'd like to think it is a rehearsal at Johnstown Castle!
According to Susan they already started filming today (without us!):
