Fox has picked up two drama pilots: a serial killer project from Kevin Williamson and a legal drama from Greg Berlanti and Marc Guggenheim, both of which will be produced by Warner Bros.

The untitled Kevin Williamson project is described as an edge-of-the-seat thriller about a diabolical serial killer who uses technology to create a cult of serial killers, and the FBI agent who finds himself in the middle of it. The Vampire Diaries co-creator/executive producer Kevin Williamson wrote the script and is executive producing.

The Greg Berlanti and Marc Guggenheim project is titled Guilty, and centers on a brilliant, morally questionable defense attorney who, after being falsely convicted of fraud and stripped of his legal license, uses his unorthodox methods to solve the cases he's been prohibited from handling and to ultimately exact revenge on the men who set him up. Marc Guggenheim, who is a former lawyer, wrote the script and is executive producing with Greg Berlanti.
