Lifetime is officially moving forward with a third film in the "Flowers in the Attic" series, based on the novels by V.C. Andrews. Jason Lewis and Rachael Carpani take over the roles of Christopher and Cathy Dollanganger respectively in "If There Be Thorns". The pair now live together as man and wife in California with Cathy's two sons (one played by Mason Cook), who are unaware of the nature of their parents’ relationship. It's unclear which, if any, other cast members from either previous movie will return for the film which will air in 2015.
