Truman Capote: It's as if Perry and I grew up in the same house and one day he stood up and went out the back door while I went out the front.
Halfway into the film, a scene shows Capote talking on a beige telephone. The receiver is a modular (plug in) type. Modular phones were not introduced until after 1966. The time frame for this movie is 1959 through 1963. All other scenes in this movie show the correct type of receiver (wired, not plug-in).
