If a mediocre film like “Highway” can make money then it means that any film in the world can make money. A film makes money not because it’s an arty film or a commercial film. A film makes money because of its marketing strategy. If you hire a good sales-person then you can sell any film that you will make. Therefore don’t worry about what if your film would make any money or not. It will make money if the sales-person knows his job .The real question that you should ask is “Do you know a good sales-person?” The director’s job is to see that the finished film is what excited him in the first place. The director can not tell anyone how to sell a film because that’s not his job. Also, nobody can tell a director how to direct a film because it’s not their job.
