Moonlight is an American paranormal romance television drama created by Ron Koslow and Trevor Munson, who was also executive producer for all episodes with Joel Silver, Gerard Bocaccio, Gabrielle Stanton and Harry Werksman. The series follows private investigator Mick St. John, who was turned into a vampire by his bride Coraline on the couple's wedding night fifty-five years earlier. In the present day, he struggles with his attraction to a mortal woman, Beth Turner, his friendship with his mentor and fellow vampire Josef Kostan, and his dealings with other vampires in Los Angeles.
The series was commissioned by Warner Bros. Television in 2007 as a presentation lasting 14–20 minutes. Alex O'Loughlin, Shannon Lucio, Rade Šerbedžija and Amber Valletta were cast in the lead roles, and Rod Holcomb was hired as director. David Greenwalt joined the staff in May 2007 as showrunner and executive producer with Joel Silver; however, health reasons forced Greenwalt to leave the series. All of the original actors, apart from the male lead role, were recast in June 2007 with Sophia Myles, Jason Dohring and Shannyn Sossamon. A retooled, full-length pilot for television audiences was then shot.
