CapoteGoofs

When the girl is knocking on the Clutters' front door we can see 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.

In the early scene of Capote riding in the passenger seat of the Chevy, a passenger-side mirror is seen. All exterior shots of the car show no passenger-side mirror.

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 close-up of Capote, the cigarette is longer.

Although depicted in several scenes 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.

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 in the movie pronounces it 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".

Flopped shot: Upon entering the chapel of the funeral home in Holcomb, Kansas, Capote sees four closed caskets. Funeral custom and casket design dictate that the body be arranged so that when a casket is opened, the head of the deceased is always on the viewers left, and the foot-end of the casket is on the viewers right. In this scene, Capote approaches what customarily would be the foot-end of one of the closed caskets. Then he opens the lid and looks inside where we see the head and shoulders of the deceased.

In the arraignment scene 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.

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.

A Close-up of a photograph in the newspaper Capote is reading shows it to be diffusion-dithered. It should be half-toned, the way all papers of the time printed their photographs.

When Harper Lee is leaving Spain, she briefly chats with Capote then gets into a cab to leave. We hear the engine start, however both of the Cabbie's hands are on the steering wheel.

In the opening wide shot of the wheat fields, we can hear strong wind gusts, but the field is still.

When Harper Lee is leaving Spain, Capote walks her out to the waiting taxi. When they both bend over to put her suitcase into the trunk, a cordless microphone unit can be seen just under Lee's shirt, attached to the waist of her pants.

As Truman and Harper drive to Danny Burke's residence you can see the reflection of the (modern day) towing car in Truman's side mirror.

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