Craven/Maddalena Films has dipped into its discretionary fund to take a dip in "Ambrose Fountain," a horror thriller written by Brian Sieve. The story follows the owners of a Napa Valley, Calif., vineyard who begin to experience strange phenomena and soon discover their property has a dark legacy that has been mysteriously buried over the years. Sieve is writing "Boogeyman 2" for Mandate. He is repped by Magnet Management and Stone, Meyer, Genow, Smelkinson & Binder.
