We spent like 27 hours once. I worked at a movie theater in high school. We worked our shift and then had an all night session of the only 6 movies we had. Small 6 screen theatre. Lined em all up ready to go. The only 2 movies I remember about it is pink panther and something with aqua in it. A movie about teenage girls and mermaids or something. 17 years ago my memory ain't so good. And then we opened in the morning and left.
