The Denver Post is reporting some signs of progress toward resolving the location issue for "When Calls the Heart" (the Hallmark project).The Hallmark Channel's ballyhooed television series in Telluride is now on its third potential filming location as production deadlines loom, but the head of Colorado's Office of Film, Television and Media is confident that filming will begin soon. "I think it's all been resolved," said Donald Zuckerman, the commissioner of the state's film office whose incentive program helped lure the Hallmark Channel's series "When Calls the Heart" to the state. "They found some private land that works, and the owner appears amenable." Producers of the family-friendly television series — the first narrative series in Colorado since 1991 — initially hoped to erect a set built to mirror 1910 Telluride on an old mining-tailings pile that hosts a not-yet-built residential development outside town. But the 120-acre Idarado Legacy project includes 37 homesite owners, and each would need to approve filming.
