The world premiere and reception for the “The American Templars,” a feature film based on the Westford Knight legend, is scheduled for 6 p.m. Oct. 12 at the Westford Regency Inn, 219 Littleton Road. The Westford Knight is a carving of unconfirmed origin in ledgerock on a hill near Westford Center; the man-made carving appears to be of a medieval sword. The film is an adaptation of the novel “Cabal of the Westford Knight,” by David S. Brody of Westford. Directed by Michael Carr, “The American Templars” is based on ancient artifacts and sites that indicate Scottish explorers found America 100 years before Christopher Columbus. The movie was filmed in Westford and surrounding areas. The reception will begin at 6 p.m., with the film starting at 7:30 p.m. After the film, there will be a question-and-answer period with the stars and director. Proceeds from the event will benefit the Westford Historical Society and Museum. Tickets are $22 per adult; $18 for those 18 or younger. The ticket price includes the reception with light finger foods and a cash bar.
