A new superhero movie was being shown in the theater during the convention, and according to the posters you saw planted all over the theater, it was going to be in something called 8-D. Some dimensional version of filming you never thought any director would achieve when going into any type of movie theater.
You also heard from most of the people who were talking that the director of the movie was also going to watch this movie in the same room the projector is in. You also noticed that the director was also getting into the costume at a convention idea to the point where he only had a black cloak that was big enough to hide everything he had. You, and your girlfriend get popcorn, chili-cheese dogs, and sodas, but no one else at the convention was interested in seeing the movie, so you got the front row.
