Andie MacDowell will be a pioneer for the Hallmark Channel, starring in the network\'s first prime-time series. Hallmark said Wednesday that MacDowell will portray municipal court Judge Olivia Lockhart in \"Cedar Grove.\" It will start with a two-hour movie airing later this year and continue with a 13-episode series early in 2013. The new series is based on books by author Debbie Macomber. Movie adaptations of Macomber\'s books have been among the top-rated programs that Hallmark has shown over the past three years. MacDowell\'s movie credits include \"sex, lies and videotape,\" \'\'Groundhog Day\" and \"Four Weddings and a Funeral.\"
