With Stephen King’s Under the Dome established as one of TV’s few hits of the summer, Encore tonight presents a Stephen King prime-time double feature, showing film adaptations from early in King’s career. The Dead Zone, from 1983, is televised at 10 p.m. ET – but before that, 1984’s Firestarter, starring Drew Barrymore as a child with a (literally) fiery temper, is shown at 8 p.m. ET. By the way: Also in this nearly 30-year-old movie, which co-stars George C. Scott, is Heather Locklear, pre-Dynasty.
