Development
At MIPCOM on October 12, 2008, the development of the project was first revealed by Constantin Film, instead of the initially planned Buffy: Vivia La Buffy sequel to the first film that was initially set to begin production in September 2008, before it was delayed and ultimately scrapped.

The plan and vision was to relaunch The Mortal Instruments as a high-end drama series with one-hour episodes and as a complete reboot of the film.[77] [78] [79] Producer Don Carmody expressed his desire to make the show a limited TV series, hoping to release a season (one per book) every year and shooting it in Toronto,[80] and Constantin Film revealing its aims to spend 2.5-5 million per episode.[81] [82] Unique Features' Bob Shaye and Michael Lynne were onboard as executive producers, as they were on the film.[78] Ed Decter was also hired as showrunner, executive producer, and head writer of the first season.[77] [81] [78] [83] [84]

Cassandra Clare first shared the series' working title "Shadowhunters" on Twitter in February 2015.[85] Along with a confirmation and extension of the title, it was revealed by an OLV source that production was set to begin in May that year in Vancouver.[86] [73] A Craigslist LA listing also put up the information of the series pilot, confirming the previous information and revealing casting notices, as well as part of the show's description.[73] Casting sides were also made available online, and some audition videos, along with speculations that came with the script portions, eventually made its way online.<sup class="reference" id="cite_ref-vids_86-0">[87] <sup class="reference" id="cite_ref-87">[88]

Author Cassandra Clare eventually met with the network that picked the series up.<sup class="reference" id="cite_ref-88">[89] Days later, on March 30, 2015, it was officially announced that the series was given a 13-episode straight-to-series order on ABC Family.<sup class="reference" id="cite_ref-THR2_82-1">[83] <sup class="reference" id="cite_ref-variety_83-1">[84]

The series is part of a broader strategic shift at Constantin that will see the German-based company move into English-language television series, one of several television adaptations of several of its English-language movie properties, including Perfume: The Story of a Murderer and Resident Evil.<sup class="reference" id="cite_ref-THR1_76-3">[77] The project also marks ABC Family's first scripted "saga-to-series,"<sup class="reference" id="cite_ref-variety_83-2">[84] and comes as the Disney-owned cable network is plotting a rebranding to target older viewers and families alike.<sup class="reference" id="cite_ref-THR2_82-2">[83]

It was soon revealed that production would take place in May 2015 in Toronto.<sup class="reference" id="cite_ref-89">[90] <sup class="reference" id="cite_ref-THR2_82-3">[83] <sup class="reference" id="cite_ref-monday_90-0">[91] McG's involvement as executive producer was then announced.<sup class="reference" id="cite_ref-91">[92] ABC Family later announced that Shadowhunters is part of its early 2016 programming, premiering alongside another book adaptation project, Recovery Road.<sup class="reference" id="cite_ref-92">[93] Production began in May (principal photography on the 25th)<sup class="reference" id="cite_ref-93">[94] and is expected to run until October 2015.<sup class="reference" id="cite_ref-94">[95] <sup class="reference" id="cite_ref-actra_73-1">[74] <sup class="reference" id="cite_ref-95">[96] <sup class="reference" id="cite_ref-96">[97] <sup class="reference" id="cite_ref-dgc_50-1">[51] Cassandra Clare has also stated that the show will be quite different from the books and is more like an "interpretation",<sup class="reference" id="cite_ref-97">[98] and that it will not be a book per season.<sup class="reference" id="cite_ref-98">[99] <sup class="reference" id="cite_ref-99">[100] <sup class="reference" id="cite_ref-100">[101] <sup class="reference" id="cite_ref-101">[102] The first season will incorporate elements from later books,<sup class="reference" id="cite_ref-102">[103] which is also supported by the early appearances of characters that appear much later in the book series.

Casting
Casting was already a priority during early stages of development, as well as a concern among fans. The first real update was released through the Craigslist LA listing posted on March 4, 2015. Alyson Silverberg, Jonathan Clay Harris, and Anthony J. Kraus serve as casting directors, and Susan Esrock and Justin Kiang as casting associates. The pilot ad included character descriptions of Clary, Jace, and Simon, all revealed to have been aged up a few years from their book counterparts.<sup class="reference" id="cite_ref-craigs_72-4">[73] The presence of casting sides online on sites such as Showfax and SidesExpress was also revealed. There is some indication that Isabelle, Alec, Jocelyn, Valentine, and Luke, as well as Dorothea, were among the other characters being auditioned for at the time.<sup class="reference" id="cite_ref-vids_86-1">[87] <sup class="reference" id="cite_ref-mcg_103-0">[104] <sup class="reference" id="cite_ref-sidespilot_4-5">[5] Some audition videos also made their way online.<sup class="reference" id="cite_ref-vids_86-2">[87] Via Twitter, McG publicized updates regarding the casting process, along with some production notes, in April.<sup class="reference" id="cite_ref-mcg_103-1">[104]

On April 20, 2015, it was announced that Dominic Sherwood was cast as Jace.<sup class="reference" id="cite_ref-104">[105] Casting of the main characters continued in May, with Alberto Rosende, Emeraude Toubia, Katherine McNamara, Matthew Daddario, Isaiah Mustafa, Alan Van Sprang, [http://shadowhunters.wikia.com/wiki/Harry_Shum_Jr. Harry Shum Jr.], and Maxim Roy landing the parts of Simon, Isabelle, Clary, Alec, Luke, Valentine, Magnus, and Jocelyn, respectively.<sup class="reference" id="cite_ref-105">[106] <sup class="reference" id="cite_ref-106">[107] <sup class="reference" id="cite_ref-107">[108] <sup class="reference" id="cite_ref-108">[109] <sup class="reference" id="cite_ref-109">[110] <sup class="reference" id="cite_ref-110">[111] Other recurring roles beyond the pilot were cast and announced after.
