The 25th Hour is the story of a drug dealer named Monty on his last day before heading to prison, so it may not be directly about the events of 9/11, but it absolutely deals with the emotional aftermath of the event.
One character’s apartment has a view of Ground Zero; the camera stays fixated on the site as he talks about being unwilling to move, despite reports of unhealthy air in the area. The entire scene is a metaphor for post-9/11 despair. Later, Monty curses out the myriad cultures and ethnicities of the city, trying to blame his problems on bin Laden, Jesus, his friends, and anyone else he can think of before accepting his ownership of his problems. The film ends with Monty’s father offering him an idealized vision of being a runaway – a vision of America that felt so much more impossible in the days and months following 9/11.
