Also on the disc
The extended director's cut restores 24 minutes of connective tissue to the 162-minute film, most significantly the last scene of Hollis Mason, the first Nite Owl. Other elements help restore and fill in details that had been in the graphic novel. Fans of the film will be glad for the extra footage but there's nothing momentous that will change anyone's basic like or dislike of the film.

The second disc has the documentary "The Phenomenon: The Comic That Changed Comics," 29 min.), which looks at the original graphic novel and its themes, and interviews artist Dave Gibbons, DC Comics executives Jenette Kahn and Paul Levitz, and cast and crew, illustrating its points with scenes from the movie, panels from the graphic novel, and parts of the motion comic. There's also My Chemical Romance's "Desolation Row" music video and the 11 video journals that helped stir up excitement leading up to the theatrical run.
