Goofs

As Capote and Harper Lee converse with Alvin and his wife at the table near their kitchen, Capote's cigarette is almost finished. In the closeup of Capote, the cigarette is longer.

When the girl is knocking on the Clutters' front door, there are two large windows on either side of the door. In the inside shot, these windows do not exist, suggesting the inside was filmed in a different house.

Early on, Capote is riding in the passenger seat of the Chevy, and a passenger-side mirror is seen. All exterior shots of the car show no passenger-side mirror.

In the kitchen, when shot from Truman's back, the martini glasses are empty; when shot from the hostess' perspective, the martini glasses are full. Truman fills the martini glasses at the end of the scene.

The car they use to drive around town keeps changing from a turquoise Chevy to an earlier model yellow and white Chevy. Sun shades on the windows are visible from inside the turquoise car, while the yellow car has none.

Although depicted several times typing furiously on a typewriter, Truman Capote was famous for writing everything in longhand. He never typed any of his novels or short stories.

Truman Capote never viewed the murdered members of the Clutter family at the funeral home, as he didn't arrive in Holcomb until several days after their funeral had taken place. According to "In Cold Blood", the detail about the heads of the deceased being wrapped in gauze was related to Capote by Nancy Clutter's friend, Susan Kidwell, who visited the funeral parlor with Nancy's boyfriend Bobby Rupp, while the caskets remained open.

Capote's hair is shown parted on the right side. All photos of Truman Capote show him with his hair parted on the left.

During the arraignment for Hickock and Perry, the flag in the courtroom has 50 stars. In January 1960, the United States flag still had 49 stars. The 50th star for Hawaii was not added officially until July 4, 1960.

According to William Shawn's sons, he did not arrange for Richard Avedon to take pictures of Smith and Hickock, did not arrange Truman Capote's reading, and actually felt squeamish about the project. He also did not accompany Capote to Kansas for the executions.

A character pronounces the river as the "Arkansaw" River.

According to a state law passed in 1881, this is the correct pronunciation, yet many people also pronounce it "Ar-kan-sas".

When Nell and Capote are doing their research in Kansas, they are looking for a girl named Laura Kinney, who is portrayed as the one who found the Clutter family on that Sunday Morning. In the book, "In Cold Blood" Nancy Clutter's two friends, Nancy and Susan, are the ones that found the Clutter family dead.

Per IMDb Guidelines, this is an "Unacceptable Goof" on the basis of: "Book adaptations: A movie is a movie and a book is a book. The movie of the book is still a movie and will be treated, for the purposes of goofs, as an entity in its own right, independent of the source material. Therefore, it is not a goof if something happens in the movie that did not/could not happen in the book, as long as it is consistent with the rest of the movie."

When Capote purchases baby food to nurse Perry Smith back to health, several of the soup can labels on another shelf have UPC bar codes and ring-pull tops.

Capote's hotel room has a plastic bottle of soda.

On the "prints" of the Richard Avedon photographs, the type of film can be seen in the black border - it reads as "Agfa APX 400". Agfa did not begin manufacturing their APX line of films until the 1990s. Moreover, Richard Avedon's preferred film for shooting portraiture at the time was Kodak Plus-X.

Harper Lee is picked up in Costa Brava, Spain, by a taxi with French license plates.

Capote complains that he has been on the "In Cold Blood" case for four years. In the next shot, he is invited to a party celebrating the movie To Kill a Mockingbird (1962). But four years after the murders would have been late 1963, and four years after he met the murderers in January 1960 would have been at least 1964.
