With franchise fever heavy in the air after last weekend’s The Hunger Games opening and the big auction for Fifty Shades of Grey, I’m hearing that Screen Gems is closing a deal to partner with Constantin on the live action adaptation of Cassandra Clare’s The Mortal Instruments, which just got Lily Collins as star and The Karate Kid helmer Harald Zwart as director. Screen Gems will distribute.

Sony Pictures, which has The Da Vinci Code and James Bond and is expected to go forward with the second installment in The Girl With The Dragon Tattoo franchise, is looking to fortify its tent pole business. The studio was one of the most aggressive bidders for screen rights to the E.L. James trilogy Fifty Shades Of Grey. Screen Gems, which has the Resident Evil and Underworld franchises, had originally been involved with The Mortal Instruments, before letting it go. Constantin put it back together. The series starts with The Mortal Instruments: City Of Bones, set in contemporary New York City, where Clary, a seemingly ordinary teenager, discovers she is the descendant of a line of Shadowhunters, a secret cadre of young half-angel warriors locked in an ancient battle to protect our world from demons. After the disappearance of her mother, Clary must join forces with a group of Shadowhunters who introduce her to a dangerous alternate New York called Downworld, filled with demons, warlocks, vampires, werewolves and other deadly creatures. Collins is about to open in Mirror Mirror for Relativity Media. Constantin announced recently that production on The Mortal Instruments will begin August 15 in Toronto.

Jessica Postigo and I. Marlene King wrote the script, with Robert Kulzer producing for Constantin Film and Bob Shaye and Michael Lynne producing for Unique Features.
