Stephen King's Silver Bullet.

“Something is killing off townsfolk in Tarker's Mills. Something mysterious. Something ingenious. Something remotely human. But the only person in town with courage to stop this lurking menace is a 13-year-old boy, confined to a wheelchair since birth. Adapted to the screen by suspense master Stephen King from his "Cycle of the Werewolf" novelette, this exhilarating thriller features astounding special effects by three-time Oscar® winner Carlo Rambaldi ("E.T.," "Alien," "King Kong").”
