That's because the movie(s) were suppose to be screened that way under the Title Grindhouse. Grindhouse is refer to the way movies were screeen in the 70s if I am not wrong. That usually mean B movies screen back to back with advertisement in the middle.
So this Grindhouse moive also has the "fake" made up advertisement...so I am wondering if they will still show them after or before the movie.
Break the show into two and make twice as much money. heheh
