David Greenwalt knows a few things about vampires who, um, moonlight as private investigators.

The co-creator of The WB’s “Angel” has been recruited to serve as executive producer/showrunner on CBS’ more-than-slightly-similar fall drama “Moonlight,” boosting that drama’s bloodsucking bona fides in the fan communities.

Greenwalt will have the chance to help “Moonlight” as it undergoes a little retooling from the original presentation that prompted the network to give it a 9 p.m. Friday home. Leading mortal lady Shannon Lucio is already being recast and The Hollywood Reporter speculates that other casting changes are possible.

“Moonlight” focuses on an undead private investigator (Alex O’Loughlin) fighting various supernatural forces while also battling very human crime. He’s joined by his former bride and vamp sire (Amber Valletta) and his vampire mentor (Rade Serbedzija). The vampire P.I. also has a budding romance with a living newswoman (Lucio in the presentation).

Greenwalt spent the first part of last season as a showrunner on NBC’s shortlived “Kidnapped.” A former writer-producer on “Buffy the Vampire Slayer,” Greenwalt’s other showrunning credits include cult favorites “Jake 2.0″ and “Miracles.”
