The Clark Planetarium opened on 11 April 2003 and was built as a replacement for the Hansen Planetarium. The ATK IMAX Theatre at the Clark Planetarium was the first IMAX theater in Utah and has 70-foot wide screen. The Hansen Star Theatre has a 55-foot domed screen and the world's first digital star projection system. The planetarium also has free exhibits, including scale models of the planets of the solar system and recreations of the lunar and Martian landscapes.
In 1976, Howard Coleman created the Lakeside Theaters by remodeling an
existing building. The theater originally showed first-run films, but
switched to sub-run in about 1985. The theater closed on 9 June 2000
because of "declining attendance and competition from the chain movie
theaters" with stadium seating and digital sound. The building, owned
by Kier Corp., was likely to be converted to retail.
