Jennilee Murray's first scene filmed in Smash Cut was the scene where Able Whitman (David Hess) discovers her dead body in the trunk. Her last scene filmed was her lap dance for Able Whitman in the Ass Menagerie.
The red Alfa that Able was driving was visibly damaged from hitting a tree the night before, yet when he drove it to work the next morning, there was no damage to the front of the car at all
In the final part of the film, when they're at the theatre to watch at the screening of "A Trilion Leaning Towers" it's clearly dark, but when they get out, after only a few minutes, there's daylight already.
Fred Sandy: Ladies and gentlemen, the announcement we are about to make has been made only three times before in motion picture history. Each time, it has preseated that the showing of motion pictures that have become reguarded as the most unsual of their type ever filmed. And now... we make this announcement for the fourth time. We are about to show you a new movie which is called Smash Cut. Watch if you must. But remember... you were warned.
