Trivia:
Dexter's boat is named Slice of Life.
Dexter frequently uses aliases that make reference to Bret Easton Ellis books and their film adaptations. These include using "Patrick Bateman" (the main character from American Psycho) when buying tranquilizers and "Sean Ellis" (reference to both Ellis and Sean Bateman - from The Rules of Attraction) when seeing a psychiatrist.
The advertisement on Foxtel in Australia promoting Dexter was pulled after the South Australian government filed complaints regarding the mention of Adelaide (a city in South Australia) having the highest serial killer count per capita.
Though they play brother and sister in the series, having met on the show, Michael C. Hall and Jennifer Carpenter married on 31st December 2008.
The name of the main character, "Dexter," is also a Latin word meaning "right hand." The implied complement is the Latin for "left hand," "sinister," reflecting his hidden dark side.
Sgt. Angel Batista at times refers to Dexter as "socio" when speaking to him as a friend or in confidence. This is a clever English/Spanish play on words. While "socio" in Spanish means "associate" or "partner", it is also the beginning of the word "sociopath" (in both English and Spanish)
Season 1 was heavily based on Jeff Lindsay's novel called 'Darkly Dreaming Dexter'. The following seasons vaguely reference the sequels of the novel.
In the finale of season three Dexter finds out that Rita has been married before. Her marriage license is displayed. It says she was born on 4/19/1989. But her wedding date is also listed as 8/16/1989, making her just under four months old for her wedding date.
