Into the Abyss (subtitled A Tale of Death, a Tale of Life) is a 2011 documentary film written and directed by Werner Herzog. It is about capital punishment, and focuses on a triple homicide that occurred in Montgomery County, Texas, in 2001. In the film, Herzog interviews the two young men convicted of the crime, Michael Perry (who received a death sentence) and Jason Burkett (who was given a life sentence), as well as family members and acquaintances of the victims and criminals, and individuals who have taken part in executions in Texas. The primary focus of the film is not the details of the case or the question of Michael and Jason's guilt or innocence, and, although Herzog's voice can be heard as he conducts the interviews, there is a minimal amount of narration, and he never appears onscreen, unlike in many of his films.

The film was first screened on September 3, 2011, at the Telluride Film Festival, and had its official world premiere on September 8 at the Toronto International Film Festival. After strong festival showings and a surge of interest in the issue of capital punishment in the United States, Herzog requested that the film be rushed into general theatrical release, which occurred on November 11, 2011.
