Martin Scorsese, the writer/director of the Taxi Driver, has admitted that this film is the cathartic result of a bevy of dark thoughts that surrounded his mind during a very low period of his life. By the time the credits finally make their merciful way on screen, we can see exactly what Scorsese saw during those days and the residual effect it has on us, the viewers, will likely stay hauntingly familiar long after we have watched the conclusion of this film.
