Open in 1908, the Isis Theatre was one of the first motion picture theaters in Salt Lake City. Its manager in 1910 was Max Florence, who a year later tried to blackmail the LDS Church by selling amateur photos of the Salt Lake Temple interior. Dan Kostopulos, a benefactor of underprivileged children, later renamed it the Broadway Theatre. In a 1976 press conference, Palace Theatre operator Lee Harper complained bitterly of persecution, made acusations of police brutality, threatened the life of a local judge, and accused the LDS Church of being involved with the assassinations of John F. Kennedy and Martin Luthar King.
Shortly after Lewiston was settled a theatrical group was formed. In 1884 the people of Lewiston built the Lewiston Opera House. It was used for motion pictures, dances, dramatic productions, basketball games, and roller skating before it was destroyed by fire in 1929.
