A&E said today that it is in early development on Bates Motel, a drama series that serves as a prequel to Alfred Hitchcock’s horror classic Psycho. Bates Motel, from Universal TV and writer Anthony Cipriano, will delve into how Norman Bates’ dark, twisted backstory from childhood through his teen years and will chronicle how his mother, Norma, and her lover damaged Norman, helping  shape the most well-known serial killing motel owner in history.

Also in development at A&E is Those Who Kill, an adaptation of a Danish series which in turn was based on author Elsebeth Egholm’s books. The project, from Imagine Television and Fox21, centers on a female police detective and a “profiler” (forensic psychiatrist), on the hunt for serial killers. Glen Morgan will write the script and will executive produce with Brian Grazer, Francie Calfo, Peter Bose and Jonas Allen. The March 2011 premiere of Those Who Kill drew almost 1.5 million on Denmark’s TV2, the largest audience for a Danish scripted series on the channel in 2.5 years.
