Never Sleep Again: The Elm Street Legacy (2010)

This was an excellent documentary and is probably going to cover any questions you would have about the series. The interviews are great and the cast and crew of every movie seemed to all have a great time with the films so they enjoy talking about the experience. This keeps the film fresh and enjoyable throughout and will keep even the most hardcore fans entertained.

The film goes through the movies one by one, speaking with various cast and crew about production and the film itself. It answers some questions and may even surprise you with some information ( IE NoES 2 having strong homosexual undertones completely surprised me. ) on each of the films. While the doc is 4 hours long, it never seems to drag and each film in the series is covered equally.

It's a wonderful companion to the series and I doubt any doc is going to come this close to being so complete and well done on any other horror series or horror flicks in general. A must own for any Freddy fan.
