“September Dawn,” as described earlier this month by the trade paper Hollywood Reporter, is “a love story set against the 19th-century massacre of a wagon train of settlers in Utah at the hands of a Mormon group.” A release from the movie's production company calls it “a Romeo & Juliet story set in the world of religious fanaticism.”

The $11 million movie is being directed and was co-written by Christopher Cain, whose best-known film is “Young Guns,” the 1988 Billy the Kid revision starring Emilio Estevez, Kiefer Sutherland and Lou Diamond Philips.

Oscar winner Jon Voight stars as the leader of the Mormon group. Lolita Davidovich (“Hollywood Homicide”) plays a member of the wagon train. Also in the cast are Trent Ford (who co-starred in the Mandy Moore romance “How to Deal”), Tamara Hope (who played Richard Gere's daughter in “Shall We Dance?”), Jon Gries (Uncle Rico from “Napoleon Dynamite”) and Dean Cain, the director's son, who played Superman in “Lois & Clark.”

The film's publicist was unable to say Friday whether Voight is playing John D. Lee, the man who led the massacre and was later executed for it, or a fictional character based on Lee. Cain, the director, is unavailable for comment until shooting wraps in late September.
