You know that scene right at the start, where Martha's washing dishes and things start to rattle?

Well... we'd been hearing thunder and lightning. I assumed it was part of the movie, because of the scene before. Right as soon as we were about to see what was up with that rattling... the power in the theatre cut out, and all we could hear was thunder as the projector died.

Eventually, after a false start, things were up and running smooth again.

Maybe it's cursed! :-o
