All of the states which bought one of Leuchter's lethal injection machines have subsequently stopped using them because they were too difficult to operate and maintain.
According to A Brief History of Errol Morris (2000), Morris made a rough cut that he showed to colleagues and friends that only had Leuchter interviewed and it was Morris' intention that the audience would understand he was saying things either as lies or flat-out wrong. He was advised to go to Auschwitz and dig deeper so that there would be no doubt for the audience that Leuchter was wrong.
The horrific execution of inmate Jesse Tafero mentioned by Fred A. Leuchter Jr. served as basis for the infamous execution of Delacroix in The Green Mile (1999), both the film and the novel written by Stephen King. The documentary and the film were released on the same week and reviewed on The Green Mile/The End of the Affair/A Map of the World/Sweet and Lowdown/Mr. Death (1999).
