Prequel to King's "Rose Red" in the works

As unlikely as I thought the idea would be, ABC are doing a prequel to Stephen King mini-series "Rose Red". Called "The Diary of Ellen Rimbauer", it’ll star Lisa Brenner and Steven Brand. Written as a first-person account by young Ellen Rimbauer, the diary documents the eerie events in the house built by her husband, oil magnate John Rimbauer, in 1907 and features many of the "Rose Red" characters. The Hollywood Reporter doesn’t specualte when it will air.
