November is a 2004 American psychological thriller film premiered at the 2004 Sundance Film Festival. It follows a photographer (Courteney Cox) whose life begins to unravel following a traumatic incident on November 7 that involved her boyfriend (James LeGros). The film co-stars Michael Ealy, Nora Dunn, Anne Archer, Nick Offerman and Matthew Carey.

The low-budget independent film was directed by Greg Harrison, written by Benjamin Brand and Harrison, and produced by Danielle Renfrew and Gary Winick. Sony Pictures Classics released it to theaters in the United States on July 22, 2005, and while its award-winning digital video photography was praised, many reviews criticized the film's story for being too ambiguous and derivative of other films. Critics have compared it to the work of filmmakers such as David Lynch and M. Night Shyamalan.

On the evening of November 7, photographer Sophie Jacobs and her attorney boyfriend Hugh go to dinner at a Chinese restaurant. As they travel home afterward, Sophie develops a craving for "something sweet" and stops their car at a convenience store. While Hugh is in the store buying some chocolate for Sophie, an armed man arrives and holds up the store, shooting the store clerk, his son, and Hugh dead. He runs away as Sophie arrives.

Sophie sinks into a deep depression, and cannot bring herself to erase Hugh's voice from their apartment's answering machine. She consults her psychiatrist, Dr. Fayn, about persistent headaches that she has been suffering from since his death. She tells Dr. Fayn that the headaches started to occur before the incident at the convenience store, and that she had been having an affair with a co-worker, Jesse. After Hugh's death Sophie has dinner with her mother, Carol Jacobs, who accidentally knocks a glass over.

During a college photography class that she teaches, Sophie sets up a slide projector for the students to showcase their best photographs. One slide in the slide show depicts the exterior of the convenience store on the evening of November 7. Sophie contacts Officer Roberts, the head of the investigation into the shootings at the convenience store, who is as puzzled as she is as to who is responsible for the photos. Sophie's headaches continue, and she begins to hear strange noises coming from within her apartment building and mysterious voices on the phone. Later, Officer Roberts discovers that the photo of the convenience store was paid for with Sophie's credit card.

The film presents two more different versions of these events, and Sophie must figure out which is real before she loses grip on her sanity, and her life. The second version suggests that Sophie was present at the shootings and was only spared because the shooter ran out of bullets, and the third suggests both Sophie and Hugh were killed. In the words of Cox, her character "goes through three phases. First there's denial. Then she feels guilty and sad about the situation. Then she has to learn to accept it." According to Greg Harrison, the events in the film were Sophie's memories as she and Hugh lay dying on the floor of the convenience store: "Each movement of this memory was her process of coming to terms with the terrible trauma, which was that she was killed for absolutely no reason, and it was some random act of violence she couldn’t confront". He added he felt November was "open-ended" enough that he hoped viewers would "come up with the most beautiful stories themselves that are very different from how I saw it."

The film's script was written by Benjamin Brand, who had written and sold several unproduced screenplays to studios. Brand had served as an assistant to producer Danielle Renfrew on the film Groove (2000), which was directed by Greg Harrison. Brand, Renfrew and Harrison were friends and living in their hometown of San Francisco developing separate projects at "Major film studios#Mini-majors" studios which, according to Renfrew, were "wallowing in development hell". Brand saw a news story about a store robbery in which the robber had hidden the body of the cashier behind the counter and then impersonated the cashier as customers came in. Drawing from this story as well as from experiences in his own life (he had previously taught photography at the Academy of Art), Brand wrote a screenplay and presented it to Renfrew and Harrison. Both were impressed, and Harrison said it was "fascinating ... kind of an abstract exercise in narrative, which I thought was exciting and bold".

Brand and Harrison worked through several drafts of the script over the following six months. Harrison, who cited the death of a close friend as one of his personal inspirations for the film, focused on inserting more emotional elements into the script; in his words they were "trying to express the subjective experience of trauma". Once a draft was completed, the group began pitching the project to various production companies. Renfrew consciously chose to avoid taking the project to major Hollywood studios such as 20th Century Fox or Warner Bros. and instead opted for "smaller companies who were interested in doing something off of center". A breakthrough was achieved after a meeting with director Gary Winick, who had established a company in New York City called InDigEnt. The company specialized in backing low-budget films shot on digital video such as Personal Velocity (2002), Tadpole (2002) and Pieces of April (2003). Greg Harrison's debut film Groove had impressed executives at the company, and John Sloss of Cinetic Media said, "November is exactly the kind of sharp and invigorating material that has made InDigEnt what it is".
