While original TV movies continue to struggle on broadcast TV as evident by the underwhelming ratings for the Hallmark Hall Of Fame film on ABC last night, the genre’s resurgence on basic cable continues. TNT has decided to extend its Mystery Movie Night franchise into the spring, greenlighting today the original movie Hornet’s Nest, an adaptation of the Patricia Cornwall novel that will star Sherry Stringfield and Virginia Madsen. The green light for Hornet’s Nest comes ahead of the debut of the TNT Mystery Movie Night, which features original movies based on popular crime novels. The franchise is set to premiere tomorrow with Scott Turow’s Innocent and continues Wednesday with the Sandra Brown novel Ricochet, starring John Corbett, Julie Benz and Gary Cole. The series will feature six movies this month and in December before returning in the spring with Hornet’s Nest and three other movies to be announced. Hornet’s Nest, based on Cornwell’s New York Times bestseller, centers on a serial killer in Charlotte, N.C., who targets out-of-town businessmen. Police Chief Judy Hammer (Madsen) pairs her top deputy (Stringfield) with a cub reporter (Robbie Amell) to address the crisis. Michael Boatman and Michael Silver co-star. Dee Johnson (TNT’s Rizzoli & Isles) is writing the script. ER alumna Stringfield is with APA and John Carrabino.
