I don't know if anyone else has this problem but I always use the loo before a movie and somehow between previews and the beginning of the movie I start squirming around. I just really have to go again! It must be now that I'm 25 I've hit this old lady hump or something! but anways there is a website http://www.runpee.com that will tell you the specific time in each movie to go for a "loo" break! So you don't miss the scene where Gerard butler gets completely naked.....or you know whatever you don't want to miss! Found the site on a new blog I was checking out ! http://whomovedmycheesestraw.blogspot.com/
Enough loo talk! Its friday night!
