The series has gained notoriety for being canceled on two occasions only for the show to be revived. The show was initially canceled by AMC in 2012 after its second season but was renewed later in the year due to a strong pitch from creator Veena Sud. After its third season in 2013 the series was canceled yet again by AMC and was nonetheless later revived by Netflix who ordered a fourth and final season.
Veena Sud has confirmed in an interview that the show depicts the different geographical locations of Seattle. Seasons 1 and 2 depict the working class neighborhoods, while Season 3 depicts the streets and the fourth season depicting the wealthy part of Seattle.
Bex Taylor-Klaus revealed on an interview that during the shooting of the third season she talked to a lot of the writers, crew members and actors to gather information about who the killer might be, to the point of actually figuring it out before the big reveal came on the show.
In The Killing: The Jungle (2013), Holder's girlfriend (Jewel Staite) comments on his tattoo "Serenity" saying that it's a stripper's name. She later says to keep the tattoo because, "It's hot." Jewel Staite played Kaylee Frye on the show Firefly (2002) and later in the movie Serenity (2005), where she was the engineer on the ship named, you guessed it, Serenity.
There's a certain piece of music that appears on every episode on the final scene. This music is a newer, a bit different, version of a piece of music from the original Danish "The Killing" series (that was also scored by the same composer, Frans Bak). Unlike the American The Killing, there was a soundtrack release for the Danish series, and on the soundtrack the music is track 10, entitled "Waiting".

The first and second season of this remake follow the plot of the original season of Forbrydelsen (2007) closely, including the many different avenues of investigation, such as the stolen politician's car, the Halloween party, the relationship with her teacher etc. This series eventually deviates and ends up with a different killer and a different motive.
