The Mortal Instruments: City of Bones, a film adaptation of Cassandra Clare's fantasy novel series, has returned to Netflix's catalogue. The 2013 film—based on the six-book saga about Shadowhunters, half-angel warriors who protect humans from supernatural threats—was directed by Harald Zwart and featured Lily Collins, Jamie Campbell Bower, and others in leading roles.

The film's commercial and critical performance was disappointing, scoring only 14% with critics and 58% with audiences on Rotten Tomatoes, which prevented plans for a sequel from moving forward. However, the source material found greater success through a television adaptation; the Freeform series Shadowhunters (2015–2018) received increasing critical acclaim across its three seasons and ran to completion without overstaying its welcome.
