The long take as Dr. Waldheim, Lt. Terri and Sgt. Cully walk thorough police headquarters when the Dr. keeps wanting to take the wrong hallway, goes down two sets of stairs and takes the elevator down to the basement morgue lasts 4 minutes 14 seconds.
The name of the book by eminent child psychologist Dr. Carter Nix (John Lithgow) wrote that became a tele-movie and a best-seller was "Raising Cain: The Creation and Evolution of the Multiple Personality".
Third and final of three cinema movie collaborations [to date, September 2015] of actor John Lithgow and director Brian De Palma. The films are Obsession (1976), Blow Out (1981) and Raising Cain (1992) - each picture made in a different subsequent decade, one each in the 1970s, 1980s and 1990s.
In 2012, Peet Gelderblom, a devoted fan of Brian De Palma, did a fan re-cut of this film after becoming aware of De Palma's regret of changing the first half of the film during post-production. The film was originally supposed to begin with Jenny's subplot of the film and the Carter Nix/Cain's subplot was supposed to emerge later in the story. After acquiring a copy of De Palma's screenplay, Gelderblom re-ordered the scenes as originally intended and it was released on the website Indiewire on January 31st, 2012 with positive feedback. Even Brian De Palma himself was very pleased with the results. So much so that when the film was going to be released on Blu-ray by Shout! Factory in 2016, De Palma was able to convince Shout! to hold off on their initial release so the Re-Cut could be included on the Blu-ray. What was just a fan re-cut of the film has now officially become De Palma's Director's Cut. Gelderblom expressed on his website how extremely happy he was.
