What’s next for Lifetime's Saturday Night Thrillers programming event? That would be “V.C. Andrews’ Heaven,” the first film in the network’s five-part Casteel Family Movie Series Event, based on the Casteel novel series by V.C. Andrews.

All five books in the collection — “Heaven,” “Dark Angel,” “Fallen Hearts,” “Gates of Paradise” and “Web of Dreams” — are getting a film adaptation, with the first one premiering tonight and a new one airing every Saturday after that until the final movie debuts on Aug. 24.

Lifetime had previously adapted Andrews’ Dollanganger series, which featured “Flowers in the Attic” and its sequels.

Now, fans are getting even more V.C. Andrews on their TV screens, with a cast over the five films that includes Annalise Basso, Julie Benz, Chris McNally, Chris William Martin, Kelly Rutherford, Daphne Zuniga, Jennifer LaPorte, Jason Priestley and more.
