Despite the fact that the massively anticipated The Mortal Instruments: City of Bones doesn't open until August 23rd, Constantin Films is already working at breakneck speed on a prequel which sounds like what a cranky old person would call a television remote - Infernal Devices.

According to The Hollywood Reporter, an adaptation of the spin-off novel series written by Mortal Instruments author Cassandra Clare, is set to start rolling with a screenplay from Stephanie Sanditz.

Mortal Instruments, a best-selling series of fantasy romance books, follows 15-year-old Clary Fray () as she becomes the witness of a murder committed by a group of teenagers with strange tattoos. As if her experience wasn't terrifying enough, she soon finds out that she was the only one who saw what happened. The killers identify themselves as Shadowhunters, a secret clan dedicated to hunting demons. Clary finds out that there is much more out than she ever imagined, and some of it is coming for her and her family, with the Shadowhunters as her only support.

As for Infernal Devices? Here's what we've got so far:

Infernal Devices is set in Victorian England and sees a new teen girl plunged into a journey of adventure and self-discovery. The books feature the ancestors of many Mortal Instruments characters as well as some character overlap.

The Infernal Devices takes place in the same universe of demons and Shadowhunters, with the characters being the ancestors of the Mortal Instruments characters. I prefer The Mortal Instruments series because the plot is more complex and I'm Team Jace because I find battle-scarred, hardened heroes, that in essence are really fragile and insecure, very interesting. He is just better than Simon. But, Infernal Devices is also a great read so it'll be interesting to see how both movies adapt for the big screen.

How do you think a Mortal Instruments spin-off will play out? Let us know in the comment section below.
