As part of its ongoing promotions to launch “Heretic,” A24 has enlisted reality stars Whitney Rose (“The Real Housewives of Salt Lake City”) and Whitney Leavitt (“The Secret Lives of Mormon Wives”) to host dueling screenings in Salt Lake City. The screening will take place on Saturday, Nov. 2 at the Cinemark Century Salt Lake 16 and XD. Attendees will be given a choice between two theaters, which reflects the one in the film offered by Mr. Reed (Hugh Grant) to the Mormon missionaries (Sophie Thatcher and Chloe East) who are unlucky enough to arrive at his doorstep.
