Amazon Studios has picked up “Carnival Row” from Guillermo del Toro and will bring it to series, Deadline reports.

“Carnival Row” stems from a major development deal Amazon Studios inked in early 2015 for the project, a TV series version of Travis Beacham’s (Clash of the Titans, Pacific Rim) cult 11-year-old supernatural feature spec script “A Killing on Carnival Row.” Amazon at the time ordered three scripts from the project, to be co-written by The “4400” co-creator Echeverria, del Toro, Beacham and Peter Cameron. Echevarria wrote the pilot script, which is going to production, and serves as showrunner. Del Toro, Beacham and Echevarria executive produce alongside Gary Ungar.

“A Killing on Carnival Row” is set in the future in a city called the Burgue, which looks a lot like 18th Century London. It is inhabited by humans and other legendary-logocreatures, and a serial killer is on the loose.

The Amazon pilot order caps an 11-year journey for Beacham, who originally sold his feature script to New Line and Koppelson Entertainment as a spec in 2005. Guillermo Del Toro and Neil Jordan flirted with the project while it was at New Line and then, following New Line’s absorption by Warner Bros., Arnold and Anne Kopelson tried shopping it to studios with Immortals helmer Tarsem Singh attached.
