After kidnapping Norman (Freddie Highmore), Romero (Nestor Carbonell) calls him a "sick f**k". This is the only time in the series that profanity stronger than "sh*" is used.
Freddie Highmore stated in an interview that this was his favorite episode of the show's entire run.
The show is based on the Alfred Hitchcock movie Psycho (1960). The song "Que Sera, Sera (Whatever Will Be, Will Be)" by Doris Day, which is from The Man Who Knew Too Much (1956) (another Hitchcock film), is played during this episode.
This episode was watched by 1.41 million viewers, making it the most watched episode of the season.
Diana Bang (Jiao), Ian Tracey (Remo Wallace), and Aliyah O'Brien also all worked on Continuum (2012) as Docent, Jason & Alyssa respectively.
