The audio commentary track that accompanies the DVD release of the film, and the "making-of" documentary ("Psycho Path") that the DVD includes, provide numerous details about where the film strived to remain faithful to the original, and where it diverged. Some changes are pervasive: as the film opens, it is made clear that it is set in the late 1990s, so minor changes are made throughout the dialogue to reflect the new timeframe. For example, all the references to money are updated (how much Marion Crane steals, how much a car costs, how much a hotel room costs), as are references to terms from the original script like "aspic" that would seem anachronistic in the new setting.
