Three Hollywood heavyweights are pumping their creative juices into the Sci Fi Channel's programming lineup, Variety reports. Horror maven Stephen King has written Firestarter: The Next Chapter, a four-hour sequel to 1984's Firestarter, which starred Drew Barrymore and George C. Scott. Hellraiser scribe Clive Barker will produce Saint Sinner, about a time-traveling monk hunting shapely demonesses on the loose. And Steven Spielberg will begin production on his long-anticipated 20-hour alien-abduction miniseries, Taken. Other Sci Fi plans include another Babylon 5 movie, titled The Legend of the Rangers.
