Seres de las sombras

Established by many reviewers (including director George A. Romero himself) as a graphic blueprint for La noche de los muertos (1968).

The first station wagon Morgan has (a Chevy) turns into a Ford (look for the 4 headlights) and back to the Chevy (2 headlights). He eventually ends up with the Ford after the zombies wreck the Chevy.

MGM's 2005 DVD release does not contain the copyright obstruction found in most prints' opening titles. It reads: "COPYRIGHT 1963 BY ASSOCIATED PRODUCERS INC. ALL RIGHTS RESERVED." It also contains the complete ending sequence, including the dialog with the baby, that is missing from most prints. This release is also digitally cleaned up, presented in wide screen format, features an interview with Richard Matheson, one of the writers, and is paired with the film Panic In Year Zero. It is missing one element common from other prints. The American International Television title card and theme music that starts off most prints is replaced with an inserted sequence of MGM's famous lion roar trademark and the MGM website address. This DVD was initially problematic on its release because of Sony's then recent purchase of MGM. Sony had canceled the entire Midnite Movies line, and, though the DVD was already set to be released, Sony had initial reservations on releasing it at all. Copies managed to accidentally get shipped to some stores, such as Best Buy, in the US and Canada, where they were immediately flagged as "recalled." Most were, either immediately returned by the stores or pulled by cashiers who should have refused the purchases. Some were still sold, regardless, in early May 2005, before they should have been. By September 2005, Sony released the DVD properly into the wide market.
