A reimagining of the cult classic, The Rocky Horror Picture Show follows sweethearts Janet (Justice) and Brad (McCartan), who stumble upon Dr. Frank-N-Furter's (Cox) bizarre abode. Frank-N-Furter, a sexually ambiguous, flirtatious alien mad-scientist - with the help of his faithful servants Riff Raff (Carney) and Magenta (Milian) - is holding an annual, Transylvanian science convention to showcase the birth of "Rocky Horror" (Nair) - a fit, attractive man created solely to fulfill Frank's desires.

The Rocky Horror Picture Show is from Fox 21 Television Studios and The Jackal Group. Lou Adler (Grammy Award winner and Rock and Roll Hall of Fame inductee) and Gail Berman (TV, film and Broadway producer), along with Emmy Award winner Kenny Ortega (High School Musical franchise, Michael Jackson's This Is It, Descendants, Hocus Pocus, Newsies), will serve as executive producers. Ortega will also direct and choreograph.
