ok guys, i know how many of us are always entertained by bluepers on movies, and this one has prob. already been spotted and notted but, just in case:
It the scheen when all the lightning and storm is going around Dana's apartment buolding, you know when the dogs get her, well when she is in her apartment look out her window, it a nice clear nights sky, no a stormy, gozer is a com'in sky, just though that was funny.

I haven't noticed anyone else mention that blooper, but I just wanted to say hi because I'm from Virginia as well

Later,
Mike

Actually that's not a blooper. There is actually a storm cloud that is just above the building and nowhere else. If you watch the scene just before you see that it shows outside the building where lightning from the cloud is just striking the building but everywhere else is clear skies. Why? Because it's a haunted house, of course.

the WHOLE sky around the building was blue!, and we heard the thunder but didnt see and flashes cept in the hall way, so it is a bluper
