JOHNNY DEPP refers to it as a "marriage of two completely different worlds" (the mix of music and horror) and ALAN RICKMAN describes it as a "Gothic black comic opera".
The 25-minute documentary is divided into brief segments that describe how and why the film was made from the standpoint of director Burton and composer Sondheim. Depp and Helena Bonham Carter and Alan Rickman, along with other members of the cast, give their own viewpoints.
The segments are: The Cast, The Vision (how it all started with a penny dreadful popularity in ye Olde England), The Music, The Costume Design (very interesting segment on attiring the entire cast), and The Production Design (which meant creating on sound stages the entire Fleet Street atmosphere of Victorian England).
Summing up: Goes by so quickly, you end up wishing for even more information.
