The untitled project is set in London in the 1800s and, "League of Extraordinary Gentlemen"-style, will follow fictional literary characters like Van Helsing and Dr. Frankenstein as they hunt vampires and stuff. Logan wrote a script for the project, with Mendes attached to produce through his company Neal Street Productions and to possibly also direct.
This will be Logan's first TV project -- Mendes executive produced "The Hollow Crown," a series of four TV movies covering Shakespeare's "Henriad" plays that aired on BBC Two earlier this year. Mendes may or may not be back for the next Bond film, but Logan certainly will -- he's on board to write the next two installments of the spy franchise. Logan also wrote the screenplay for "Noah" with director Darren Aronofsky.
