The budget for this film was about two million dollars. Half of that was to secure music rights.
The hot rod Lincoln Continental and the off-road race car belong to Dax Shepard in real-life. Also, since the movie was an independent production with no studio supervision, Dax also did his own stunt driving.
Dax Shepard made this movie with a bunch of his friends in the business. This included his real-life girlfriend Kristen Bell, who played the same role in this film.
Because of the small budget, many of the cast members did their own stunt driving.
