The Runestone is a 1991 adventure/horror film, the first film written and directed by Willard Carroll. The film is an updating of the Ragnarok legend, with Fenrir being found in a runestone in Pennsylvania unearthed by archaeologists. The film is based upon the novel by Mark E. Rogers, which has never been published.
Sam Stewart and wife Marla (Joan Severance) find it has some connection to their friend Martin. A young boy named Jacob (Chris Young) is haunted by terrifying nightmares of what is to come, and his grandfather (William Hickey) explains these dreams through stories from Norse legend, which says that the only one who can destroy Fenrir is Týr, the Norse god of single combat, victory and heroic glory, who is prophesied to return to fight the creature. In the nick of time, the mystical Clockmaker (Alexander Godunov), who actually is Týr, one-handed Norse God of combat, begins fighting Fenrir. The film cast includes Peter Riegert as a Pez popping, cussing policeman, and features a cameo by composer David Newman as a police officer named Strange.
