 After 14 years, "The Dark Knights First Night", the rarely seen  pilot promo reel developed for Warner Brothers by  Bruce W. Timm (qv) and Eric Radomski (qv), was included on the  first DVD boxed set. Versions of the promo had surfaced in degraded  bootleg form at comic conventions over the years, but was never  intended for public viewing. Unfortunately, the actual Warner  Brothers reel was not kept in the best condition either, appearing  at around 105 seconds in length and having been converted from VHS.  The original Audio track was lost over time and replaced with the  shows main theme for the DVD.
